My LO is 5 weeks old now, and this week he has started fussing whenever I put him down. He is in a good mood in the afternoon/evening as long as he gets enough sleep during the day. If not, then he is fussy all evening until he finally falls asleep for the night. What's odd (in a good way) is that he sleeps good at night. He wakes up every 2.5-3 hours at night but goes right back to sleep after he eats. I keep the lights off when I get up at night and dont talk very much so he stays drowsy. Anyway, during the day he can sleep for hours while Im holding him, but if he is awake and I put him down he will fuss, and usually if I put him down once he is asleep he will wake up and fuss. Any other mamas dealing with the same thing? Any advice how to keep him asleep once I put him down for a nap? I figure the crying when I put him down is a phase that will pass, Im not too worried about that (its exhausting, but I dont mind getting all the snuggles), but I just want him to stay asleep when I put him down during the day. He is grumpy when he is overtired!
