My newborn is a week old today and has so far been great at breast feeding. He was weighed again at 5 days old and is almost back to birth weight. The since Thursday evening he has been eating every 4 hours and I have found I am needing to wake him to feed him. He seems to be getting enough....just gulping it down haha and feeds for approx 12-20 mins per side. He is not fussy at all during the day unless he needs to burp. Should I be concerned I am needing to wake him to eat? Is every 4 hours okay? I know that can change by even tomorrow morning but just want to check. When I do wake him to eat he is content and latches right away.... He doesn't seem over hungry. First time mom by the way. Thanks!!! 😊
