I know this is easier said than done, but what I did to get my little one to sleep through the night was not responding to her. I let her cry. It was so heartbreaking, but after many sleepless nights this is what I had to do. Your child will get it after a couple of nights of doing this. By the way I do not reccommend this for a child younger than two years. You may want to have him sleep with his favorite stuffed animal every night. If he doesn't have one let him choose one to sleep with. He will get attached to the stuffed animal and feel more comfortable and at ease when he has to go to sleep. Make sure it is the same stuffed animal every night. Also it is best to make it a routine that he goes to the potty right before bed to avoid accidents.
