Almost 3 weeks old... we do well with our feedings every 2 1/2-3hrs during the day. Few minutes of play then right back down for nap. Night time sucks!! His last feed is 9:30 and makes it until 1am or so. We eat, then he’s wide awake. Started rocking him for 20mins before we lay back down and it’s helping putting him back to sleep. Then an hour after feed we have spit up, out the nose and mouth and it’s just a scream fest for another half hour before we settle again. By this time it’s 2:30, baby up again at 5 bc hungry. Once again same process until 7 with the spitting up and not settling. He doesn’t do this at all during the day! No spitting up what so ever. Swaddle causing reflux? It just seems so much later for spit up. Any advice?
