So my 3 year old flips out when he gets tired. He screams, calls names, hits, everything you can think of. It's absolutely driving me crazy. He will do it until I finally sit down and hold him to keep him from moving, them he will scream and fight me for about 10ish minutes and fall asleep. Any advice on how to get him to stop? And, if this is normal behavior, please please please tell me it will pass!!
