My little one is a few days from being 10 months old and he is learning new things every day. He's usually a very good sleeper, but lately he has started sitting up either a couple hours after I lay him down or really early in the morning. It's almost like a sleep sitting up because he cries when he does it. Unfortunately, he doesn't know how to lay himself back down so I have to go in there and lay him down, and then he cries because he wants me to hold him. Anyone know how to teach your baby to lay back down or any suggestions so this doesn't become a habit?
