My daughter is 5 weeks old and has been gaining weight great. I feed her every 2-3 hours during the day. She's a sound sleeper at night and I've been letting her go one 4 hour stretch between feedings each night. I was wondering if I still need to wake her up at night to eat, or if I should just let her sleep and feed her when she wakes (of course that means waiting until she cries, which I know isn't the best way to start a feeding.) Last night I forgot to set my alarm and she went 6 hours between feedings! Also, will my milk supply be hurt by going this long between feedings at night?
