Thanks guys!
I have tried to reassure DH and he was even able to say that he is trying to tell himself that it isn't a big deal but it is breaking his heart and it is so hard for me to watch.

The hardest thing I think is that DS is choosing not so much to go to me, but rather to go to other male family members (uncles, grandfather, cousins) whom he sees even less then his father - rather than spend time with his father.

He is a curious, active little boy and so is often looking all around the room at things rather than people sometimes and that frustrates DH as well - especially when he wants DS to look at him and acknowledge him.

I hope and pray that it passes soon as my DH has enough other issues on his plate right now without this too. He hurt his back and his elbow and he is having stress/issues with his business and I'm just at a loss as to what to do to help him.

Add to the fact that my MIL has been staying with us for 2 weeks and we have had little or no privacy and things are just really building up for him I think.
