Hi, I have an almost 7 week old and I am breastfeeding. For the first two weeks I breastfed her and also expressed as she was in hospital. I got up twice in the night to pump. When she came home she slept through which she has continued to do. She's always had one formula feed at 11:30 which my husband wakes her up to do. She cluster feeds from me about 6-8. I wake her up at 7am so I go from 8pm-7am without feeding or expressing. My boobs have adapted to this. However, I keep reading that not expressing or feeding in the night will drastically reduce supply. Now I understand this is the sense that it will stop producing the extra milk that baby may have needed in the night which is fine obv cuz she's asleep but it makes out like this is an awful thing to do if breastfeeding. I thought breastfeeding was supply and demand so my boobs will make what my baby needs so I just don't get it and it's stressing me out. She feeds fine in the day she does feed a lot and for long periods of time.
