DCs are 10 and 8. DS's two Godfathers are his uncles, his Godmother is a friend. DD has three family friends as Godparents. The two uncles buy gifts for both DCs. DS's godmother asked a few years ago if I minded only doing birthday gifts (I'm her DC's GP too) which of course I don't mind. But DD's 3 God-parents all buy her gifts for Christmas, so every year DD gets three more Christmas presents than DS. This has only caused minor, occasional irritation from DS to date, but today, DD opened a card to find a substantial amount of money from one God-parent and DS was understandably a bit upset.
Part of me feels that DS is just going to have to live with it, but it really doesn't seem fair (it never even crossed our minds when we chose the GPs). Part of me feels that we ought to make it up to him to some extent. WWYD?
