Why does my baby fidget so much In his sleep?
When he wakes up, he will learn to put himself back to sleep if you don't interact with him. If you want to sleep with him, that's fine, but if you don't, don't start it.
If my child started doing this, i'd just leave him in his own bed and see if he settles back to sleep in a few minutes before i did anything else. My kids didn't sleep with me at all when they were that young. Kids need to learn that bedtime is time to be independent. Plus, i don't want my kid to think i cant do anything without him, even sleep. When we have babies, we do lose sleep. It happens.
He's learning a new skill (moving around on his own). He'll get through it.
There are plenty of parenting books out there!
Leave him alone if he's sleeping good grief
You're getting into a vicious circle. If you had left him alone in the beginning, he would probably do that for a while and then stop, but now that you have started patting him because of this, he fidgets now expecting you to pat him. If he is not waking up, and is not doing himself harm, let him go. He will move on from this when he is ready.
