First Christmas as separated dad

Let the children decorate their bedroom for Christmas at your sons so it feels like theirs. Have duplicates of some of their favourite toys and games at both homes.

Be relaxed and child led having high expectations can only lead to disappointment.

Even if he doesn't actually have them on Christmas Day, do all the Christmas things - pressies, tree, decorations, dinner etc.

One of those gingerbread house kits that you stick together with any icing that hasn't already been eaten!

Games if they like them.

Skype or whatever with members of his family.

A walk to see lights if there are any nearby
