Hi D., the other moms have good ideas, but honestly I would let him adjust in his own time. When we moved from San Diego to Sasebo Japan I thought for sure our kids would have a hard time adjusting, not only a new house, it was going to be a new Country. At that time our kids were 7, 4, and 22 months, and most of the stuff they were familar with was packed, so here my kids were different house different country, with most of their belongings still packed, adjusted with no problems at all, and i was told by another woman that I met who's daughter had adjust very well as well, that her daughter and my kids found their security and their place with us the parents, not in their house or their stuff. Now I'm not saying your son doesn't get security from you, but it does seem that the biggest part of his security is with his house and things. Give him time to adjust, usually if children see mom and dad happy in a situation they usually feel secure and are happy themselves. I don't know if you did this or not, but we sat our kids down and we talked about the move, and the packing, even the over seas shots they were going to have to get, everyday at dinner, we let them ask question, we let them share their feelings, so when the big move came, they weren't thrown, we had talked about everything ahead of time.
