My 10wk old only naps for 45 min at a time. He is not UT or OT- I catch his cues right on time. For the first 8wks he fought sleep by SCREAMING for hours he then went through a two week phase of easily going to sleep and getting at least 1-2 long naps (about an hour and a half to two hours each) a day. Suddenly he now fights his naps again and only sleeps in 45 min chunks and stays awake for 45 min before becoming tired again. He is obviously tired throughout the day bc he isn't getting restful sleep. He is also now waking more often in the night. He used to sleep from 7pm- 1 or 2am and then until 4:30 and then until it was time to get up at 6:30. Now he fights BT and doesn't fall asleep until 9:30 and then wakes every hour from midnight on. Is this a developmental stage or is there something I can do? Please help! I write this as a SH pat a SCREAMING baby!!!
