The "pump today for tomorrow" method really helped many mums I know, basically your baby drinks whatever you pumped the day before, so you're always one step ahead and it takes the pressure off building a huge freezer stash. The key is keeping your pump sessions at work timed as close as possible to when your baby would normally feed, because your body responds to consistency more than anything else. Some mums find it manageable, though a few mentioned the hardest part is not the pumping itself but the washing and sterilising on top of night feeds, it does add up, so be realistic about what you can sustain. If you can, start practising with the pump a few weeks before you return so your body is already used to it and you have a small buffer stock ready. Any amount you manage is genuinely worthwhile, so don't be too hard on yourself if the routine shifts a little once you're back at work.
