My baby is 5 weeks old and feeds (bottle fed) every 3 hours through the day and currently 4 hourly at night (11pm to 8am say). He's putting on weight at the right rate so no problems there. My question is do I have to wake him through the night for his 4 hourly feeds or if he sleeps past it is it ok if I leave him to sleep and just feed him when he cries eve if this is much longer than 4 hours? I'm confused as to what I should do. Obviously the less feeding through the night the more sleep I get but what's right for my baby?
