Gave birth at 8am this morning and baby had a little feed at about 9am. Since then he's just not interested. I've tried a couple of times but he won't take the nipple even though he obviously knows what to do. I just want some reassurance that it's ok because i don't think their appetite kicks in yet, does it? I don't want to delay my milk coming in because he's not nursing. All opinions appreciated. Thanks!
