You have got to keep letting other people watch him he will pull out of it. But if you stop leaving him you are going to have even more troubles with him. Just do it little at a time. An hour or so here or there then work your way up. I have gone threw this with my kids and I am a daycare provider so I have seen this many times. Keep your chin up he will come out of it I promise but dont stop leaving him!!!
