Bottle of formula overnight?

KSandra

My little girl was born 4 weeks early and so we have some feeding challenges - she gets very tired feeding and so I express after every breast feed, give her an EBM top-up through a bottle and wake her every three hours round the clock to make sure she gets enough food which gets exhausting.

The last two nights my husband has taken the midnight feed - I am making just enough milk to satisfy her (I can express 50-80mL post feed from one breast) - but there’s not enough left over to give my husband a EBM bottle so he’s been giving her a bottle of formula. The extra sleep is helping me enormously (I sleep from after her feed at 9pm until her feed at 3am) but I feel guilty missing a feed and I’m worried it will eventually affect my supply. Thoughts??? Am I being selfish?
