My 7 month old DS has been sleeping thru the night (8PM-7AM) since4 months. For the past 4 days, he has woken up at 4 am crying, and is having the hardest time getting back to sleep!
I cannot identify any cause for the wakings...routine has been the same, no new foods, no illness...and he seems WIDE awake!
Should I continue with PU/PD when he is not crying, unless I walk away? Should I go into his room at 3:45 and start "whispering" before he wakes up?
