We are on the opposite side -- my soon to be 6 yo. just moved away from 2 best friends that he has had since he was almost 3.<br><br>
I'm not sure how either of his best friends parents' dealt with it, but I know that both of the friends knew. I know that first instinct would tell you to maybe start limiting play with the friend so that the move would be less important when the time comes. But I tried to do the opposite - increase chances for playing so he had plenty of chances to say little good-byes. I took a lot of pictures and made a little photo album for my ds of all the familiar faces and places. It has been a source of comfort for him when he gets a little lonely. On your side, however, I would start to look for "substitute" friends to fill the void. Also -- there has to be books at the library about friends moving away. I'd ask your librarian for a suggestion.<br><br>
My ds is a little older, so phone conversations and letters are a possibility and even emails. He hasn't suggested any of these yet and it's been a month since we've moved. He has talked about his friends and today he did a little pretend game outside where he was looking for one of them as part of the play. It's hard on both sides - for the one who's moving and the one who is left behind.
