My 8 week old has started feeding every 2 hours even at night. I've heard that by now she should be sleeping much more throughout the night. She will go for about 3-4 hours once during the night, but after that it's 2 hours--like clockwork. When she was a week old, she had lost so much weight, that the doctor told me to supplement with formula. I did that until she gained enough weight to go strictly to breastmilk. But then she was eating every 3 hours. I'm thinking about giving her formula again at night so she'll sleep more. Has anybody else dealt with this? I could keep it up for a bit longer if I knew there was an end in sight.
