My son is a week old and right now he is eating nonstop during the night and mornings, like literally every half hour it just seems like he is never ever satisfied when I breastfeed him. However, during the day and evenings he is sleeping the entire time. His diapers are good and has anywhere from 12-15 a day and I know he is putting on weight. So my question is, should I wake him up to feed or just let him sleep during the evenings? The hospital said feed him ever 2-3 hours but his pediatrician said whenever he is hungry.
