My LO is 13 weeks, we can put him down for bed and he will put himself to sleep and put himself back to sleep if he wakes up again up until midnight. Then after that, he’s up every 2 hours on the dot fussing and fussing turns to crying. We wait it out to make sure he’s truly awake but once we go in we put the pacifier back in and rock for 3 min and he’s back to bed. What is going on??? Granted a lot has changed, he’s no longer swaddled (we transitioned him to the zipadee zip 5 days ago), he’s starting to roll and grab. Before all this he would sleep 7-8 hour stretches. Did this happen to anyone else’s baby?? Do we just keep doing what we’re doing??
