FTM. Newborn and breastfeeding

K

Sometimes my 5 day old will only been on my boob for 5 minutes before passing out. Other times he will feed for 20 minutes. I try to feed him every 2-3 hours. I’m just so scared he isn’t getting what he needs. I feel like the flow is pretty good, it always seems to leak all over his bare skin and is all over his chin. (I change him before feeding and usually just have him in his diaper to keep him awake.

But then again he is happy, sleepy, pooping and peeing ALL the time. So Am I just being paranoid?? He only ever cries while being changed or when he is hungry.
