Unfortunately.....you leave him alone and stop going in there. You are reinforcing a habit that has nothing to do with him standing in the crib but rather him knowing you are going to come in there and see him or console him if he's screaming and standing up. Trust me, this guy will tucker himself out and his little legs will not even want to be standing anymore when he does. He will simply sit down and hopefully stop the carrying on and soothe himself to sleep like he should. He's 10 months old now. It's time to institute the tough love and let him work it out. He's safe, he's in a comfy place that is meant for calm and sleeping. He needs to be getting himself to sleep on his own and no more nighttime tactics to get you back in the room for visits. I hope you realize that this is what he's doing. If he can get up....he can also get down. And he will. No more night visits. Cold turkey this and I swear that he will stop all the middle of the night drama in about 3-4 days. Simply put him down for the night and do not go back in to his room until morning. It's not harsh....it's teaching him to sleep. You need sleep too. You can do it, Mom.
