I suppose we had a sort of routine at 11 weeks when C started sleeping through. I'd spend most of the evening on the sofa feeding him between short naps, then give him a final feed when we went upto bed about 10.30, and he'd sleep until about 5-6am when he'd BF again. Throughout the day it was all a bit random though.
Re expressing, I started at 4 weeks and gave him occasional bottles of EBM from then (once or twice a week). Luckily he wasn't bothered where his milk came from so didn't have any problems with that, and my supply seemed to cope with it fine. x
