Breastfeeding Guide – Expressing Milk at Work

UPDATED: 5th August 2015

I’ve wanted to write this post for a while. And I’ve probably put it off because I was worried that people may not want to read about it and it could alienate people or even make some feel uncomfortable, but I really want to try and help. So here we go…

I went back to work when my son was just under nine weeks-old. I’d been exclusively breastfeeding up to that point and, while initially I didn’t think I’d make nine days, let alone nine weeks, I knew straight away that I didn’t want to stop. My little boy really enjoyed it and so did I. So I started expressing at work.

In the end, we managed 18 months. And I couldn’t be prouder of my achievements.

But I had some real ups and downs, and one thing I really wish I’d had was information, all in one place, that I could refer to. Some websites like are useful, but I wanted first-hand information, because sometimes it was a stab in the dark and I felt alone.

So here are my tips. I hope that they will come in useful for those like me.

An Expressing Kit

  • A Pump – I had two. I had both the manual and electrical Tommee Tippee Closer To Nature pumps. Both of which I found simple enough to use. Two may sound excessive, but they came in useful for two reasons. Firstly – my electric pump broke and without my manual one I would have probably suffered with blocked ducts, a drop in supply and mastitis. Secondly – after my pump broke and was replaced, I realised that it was far quicker using the two simultaneously. It did take some balancing and a little hand-ache on the manual side of things, but it made things much easier for me.

Note: If your Tommee Tippee pump breaks, you can call the Tommee Tippee Customer Service team to arrange a repair/replacement – 0500 97 98 99 – couldn’t recommend them enough. Also, if money is tight, try second-hand pumps, or see what parenting magazines are giving away when you subscribe. Sometimes a pump will feature! 

  • Microwaveable Steriliser & Bottles – Again I used the Tommee Tippee Closer to Nature Kit and this worked perfectly for me. I would bring two 9oz bottles and usually fill them, if not more every day.
  • Breast Pads – I stupidly thought I wouldn’t need them, but, while my gals adjusted I would get let-downs throughout the day and there’s nothing quite like the shame of a milky patch shared with your colleagues. I liked the Lansinoh, Tesco (best for quality and price) and Boots ones, but Sainsbury’s were AWFUL.
  • Milk Bags – I used both the Lansinoh ones (bought from Amazon here) and the My Baby ones (which you can purchase here, or from Home Bargains for slightly cheaper). I always had these to hand in case I over-produced and I would also use them to store my stash in (whether that be in the fridge or freezer at home)
  • A Clean Muslin – Expressing can get a bit messy and these are as handy for your leaks as they are for your baby’s!
  • Water – It’s thirsty work!
  • Entertainment – I used to watch YouTube videos on my iPad to help pass the time (it’s boring stuff!).


Before you go back to work, you need to do the following:

  • Introduce your baby to a bottle and make sure they happily take it from a range of people. I made sure William took a bottle of expressed milk every week from three weeks old (I waited until then to ensure there was no nipple confusion) until I went back, with a few extras the two weeks before I returned.
  • Get your breasts used to a pump. Sounds simple, but pumping is so different from breastfeeding. I started expressing when he was three weeks and at first I’d get a little at a time, sometimes not more than an ounce, but slowly, after every feed, I would express and encourage my girls to make a little more milk. In the end, I would easily get around 5oz-7oz as well as exclusively breastfeeding. By the time I returned to work I had over 150oz in my freezer, ready for emergencies and in case expressing at work didn’t work for me. This was like a comfort blanket to me and I would really recommend having a stash ready.
  • Get a special expressing bag (I just used a hemp Tesco bag-for-life!) and get everything ready in there, the night before work, just so you can grab it and go and you don’t leave anything by accident. 
  • Notify work with plenty of time. I did this via email to keep things documented and professional. My employer was very flexible with me and it made everything a lot less difficult for me. I have a friend whose HR team told her: “One rule for cows and another for humans.” She stood her ground and I provided her with a series of links to support her case and she happily won. There are lots of benefits to employers if they allow employees to express according to the NHS – including reduced time off as breastfed babies are generally healthier (according to the NHS, not me!),  increased staff morale and loyalty, and a subsequent higher rate of return to work, lower recruitment and training costs; and an extra incentive to offer potential employees. Don’t be afraid to fight your corner.

Note: The HSE states: “You should provide your employer with written notification that you are breastfeeding. It is advisable to do this before you return to work, so your employer can ensure you return to a healthy, safe and suitable environment. It is not suitable for you to use toilets for expressing milk. Your employer may provide a private, healthy and safe environment for you to express and store milk, although there is no legal requirement for them to do so. However, your employer is legally required to provide somewhere for pregnant and breastfeeding mothers to rest and, where necessary, this should include somewhere to lie down.”

True or False

If I take this entire pot of Fenugreek I’ll make enough milk to feed the whole of Manchester’s babies. FALSE – I didn’t find it did a thing, bar make my wee smell.

Drinking lots of water will help your supply.
TRUE – Okay so it wasn’t a milky Niagara Falls or anything, but if I didn’t drink enough, I found it took longer to get my ‘usual’ amount.

If I get less today my supply is dropping and will soon dry up.
FALSE – At least on most accounts. My supply went mental during growth spurts, so much so that some night I would express before going to bed just to get my extra milk. It became a bit of an obsession, but a few days later, it would be back to normal. A good reason to build up a stash before you return though.

I’ll just eat lots of breast-milk cookies – that will help.
FALSE – My friend made me some lovely cookies, based on this recipe here. But they just tasted nice. In fact, so nice, my colleagues munched their way through too. None of us made lots of milk though. A good diet, with plenty of water, fresh fruit and veg is all you need.

Breastfeeding my baby whenever possible will keep my supply strong.
TRUE – I am the only person ever to have done a night feed. It was a sacrifice I made and it wasn’t easy (my son didn’t sleep through until a year old) but it kept my supply strong. Your breasts will never react to a pump in the same way as they do your baby – it’s all about emotion and endorphins. And love. Corny, but true. It’s hard, but trust me, it’s worth it.

My Schedule

Nine Weeks to Six Months

  • Fed through the night when he needed it (I should warn you that some babies, when their mothers go back to work early, reverse cycle).
  • Feed him his breakfast (both boobs).
  • Express both boobs at around 11:00am-12:00pm, depending on how work goes – average around 10oz. His morning feed for the next day.
  • Express both boobs again at around 3:00pm – again 10oz. His afternoon feed for the next day.
  • Feed him when I get home from work – 5:30pm.
  • Feed him at bedtime – 7:00pm.
  • And sometimes at night! 

Six Months Onwards

Around Christmas 2012, my son turned six months and I had two weeks off to get myself used to dropping expressing during the day. He was weaning well and expressing had become a very hard thing for me to do. So I made the decision to use up what was left of my stash (which ran out in February 2013) with a view to moving him onto formula during the day, and breast whenever he was with me.

He hated formula though. With a passion. But took to weaning (we went with baby-led – you can read about that here) so well that he didn’t miss his daytime feeds and preferred to have water and lots of food instead. Babies tend to drop these feeds at this age anyway, so I encouraged food, which he took to happily.

I fed him his first feed of the day, a feed at 5:15pm when I got home from work and a bedtime feed. He also had breakfast, lunch, dinner, water and snacks throughout the day.

Note: Your boobs will survive this transition. At this stage you supply on demand. Some weekends he will ask for more and I’ll give it and they adjust accordingly. I’ve never had mastitis or any problems because of it. 

Useful Tips

  • Make good use of your freezer. I would express enough for two 9oz bottles and some smaller ounces to keep as top-ups where needed. I would leave one bottle in the fridge and then defrost 9oz of my stash from an earlier date and replace it with freshly expressed milk from that day. It meant that none of my milk went out-of-date and it lasted so much longer. Breast milk lasts for five days in the fridge and up to six months in the freezer.
  • Don’t stress. Easier said than done I know, but it doesn’t help your supply. 
  • Babies have growth spurts, so expect your supply to rise and fall accordingly. Don’t panic.
  • If your expressed total is low, try and squeeze in an extra session just before bed, while baby is sleeping. It’s not the first thing you want to do at that time of night, but it’s easy to sit back and let it happen and just relax.
  • Always pack your bag the night before. You don’t ever want to be caught short the next day – because not only will your baby not have any milk, but you run the risk of discomfort, blocked ducts and even mastitis. 
  • If at first you feel awkward, try to relax. Stick YouTube or iPlayer on and catch-up with some programmes you never have time to watch. Or look at photographs of your baby, it does help you to relax and to get things going.
  • Always take a drink with you. Nothing worse than being thirsty locked in The Milking Room.
  • Be proud, not ashamed. Your colleagues will be curious – being open with it is far easier than scurrying away with your head down. And also, don’t feel guilty, you are a hard-working individual and if anyone raises an eyebrow, just point out toilet or smoking breaks. Or, you know, tell them they are idiots.
  • Stop if you don’t enjoy it. Formula, no matter what we are led to believe, is not poison. If the option is there, embrace it. Happy mummy – happy baby.

Well done if you managed to read all of this! I hope it does manage to help someone, as I know I’ve never felt so worried or stressed in all my life when I was getting used to expressing at work. If anyone has any questions, needs advice, or someone to talk to, please feel free to email me at [email protected] or tweet me at @CharlTaylor.

    Hi Charlotte, thanks so much for writing this, really interesting! I really admire you going back to work so early. My little man is nearly 9 weeks & my brain cells are nowhere near previous operating level yet! I am planning on expressing and freezing so when he weans he can have expressed milk in a bottle but am unsure as to when to do it and what quantities I should freeze in – do you have any ideas? X

      Becca, your comment has made my day – I was so worried about writing this as it's not my usual sort of post!

      Of course I can help! When are you looking to wean? For a rough idea, William had three 5oz bottles a day when I was at work, but then quickly moved up to 9oz by about four months old. When they start to wean, they tend to only need a breakfast, lunch and dinner feed (as well as night feeds if they want those too). I would trial and error and freeze a few 9oz and see initially how much he takes, and also do a mixture of 1oz, 2oz, 3oz, 4oz, 5oz. Because if he prefers to have 6oz or 7oz you can easily take out a few assorted bags to make up a bottle and then, when you are certain what amount he takes, you can just make those bags up in full the next time you express. It also helps to have a few extra single or double ounce bags there for mixing into baby porridge and puree if you go down that route too. Does that help? I hope so! 🙂 xxx

      Hiya – I think its brill. Theres lots of general advice out there but not really any specific experiences of mummies & I think its always better to hear how people managed it! Im not entirely sure when to wean, lots of things ive read say around 5/6 months, but then some of the mums at baby group started around 4/4.5 months…so was just planning on deep freezing until he shows signs of wanting to try food. So confusing and just want to do the best for him!

      We weaned at six months and, as we went down the baby-led route, it was the best thing for us as there were no off-limit foods. I've done a post on it, if you flick through a few past posts. May help a little! And I think it's best to follow his signals. As he'll be ready then and it will be exciting and fun for both of you. 🙂 xxx

    Char, you're tips are great. I stopped breast feeding at 6 weeks and did a lot of expressing, I would have found this incredibly useful while finding my way in the baby world. Great post.

      Thanks Helen. That means so much! I have wanted to write it since I stopped at Christmas, but I've been nervous! I just thought it would be very alienating! But I'm so glad I did now, especially thanks to your comment and Becca's above. Thank you chum! xxx

    This is fab Charlotte! And just what I needed before the baby arrives! I definitely want to BF but want hubby to be able to feed him, so I want to express some too. I also want to continue BF for a bit (along with weaning) when I go back to work in September, as he will only be 6 months old. So your post was just what I needed to get me started! xx

      I'm so excited for you! Though not as excited as you must be, I'm sure! I do hope this helps. If you ever have any questions once baba is here, you know where to come right? I'm no expert, but if I can help, I will! xxx

    Hi, I mentioned this on twitter @effinbroccoli) but I just wanted to reaffirm how useful this post is. I'm 'combination' feeding my 9 week old, as after mastitis and blocked ducts I've had supply issues.I've been thinking of giving up breastfeeding entirely but having read this post and your determination to keep breastfeeding after returning to work, which cant be easy, I'm going to keep going with the breastfeeding! Its great you're talking about the practicalities of it all. Thanks! X

      Thank you Georgie! It may sound silly, but knowing that it's already been useful for a few people already has really made this worthwhile for me. I hope that everything works out for you, I really do. I was very lucky not to have suffered with mastitis, but I can't imagine how painful it must be. If you ever want to chat about anything, please do tweet or email me. I'm really no pro, but I do want to help where I can. Breastfeeding isn't as easy as people make it out to be. At all! 🙂 xxx
