I pump at work and BF at home. My schedule is thus:
4-5am BF (yup! I know...) usually a single boobie.
7-8am BF usually a double boobie.
at work
10-11am pump. Yield around 200ml total. I use a Medela Freestyle double breast pump and I only pump for 10mins.
1pm sometimes OH brings wee one in for a feed - usually not though. If I feel full (not every day) then I just 'take the edge off' and pump 50ml off.
3-4pm pump. Yield about the same as before.
Home for about 6.30-7.30pm then immediate boobie when I get through the door. Single boobie
Solid food feed, then bath (yes - I know, food before bath, but we're doing baby-led so stuff ends up EVERYWHERE and there is truly no harm in bathing your baby after they've eaten).
Boobie to sleep for 8-8.30pm. Single boobie.
Up again at 11.30pm ish, and 2ish for a single boobie.
So. I bring home around 400-500ml of milk a day. OH lets the wee one choose as and when he feeds and he rarely has all the milk I supply. Wee one will no longer take my frozen stash (fussy little poo) but will take my milk if it's no older that 2 days old. We tend to bin the previous days milk if it's not drunk.
I think the take home message is that your baby will be fine. Usually they'll be like my wee one and make up for lost boobie when you get back in. It's a great excuse to have more 'close' time and there's nothing like baby cuddles and nursing to relax you after a long, stressful day at work.
All the best.
