don't stress about it, make it fun. don't talk about it too much, until maybe a week or so before (as long as you can put off packing his things - do his room last), then when you do start with his things, have him help you and make it very positive. mine (we did move when he was 2 - actually we had to because of a fire - our apartment was fine but it was structurally unsound so we had to go) didn't even care about the rest of the rooms being packed up, i just went about my business as if it was completely normal. of course save all his favorite things for last (even the day of or the night before if possible) and my best advice is to have him spend the night with grandma or someone else that he loves and trusts, on moving day. when he goes with them, prepare him, maybe have him say good bye to his room, and tell him that (in my son's case), Giraffie, Buzz Lightyear, his race cars, his trains, all of them are going to go with us to the new house and we will see them there. it can be upsetting, i'm sure, but when we moved, he was the least of our worries - he was totally fine. either i got a great kid (well obviously hehehe) or it was in how we handled it. the less stressed you get, i believe, the better off everyone will be. good luck and congrats!
