We have plenty of presents for the DCs and they will be visited by Santa on the day 
But my parents have spent about £120 on the DCs presents and they are lovely presents. We will not be seeing them this year on the day but will on Boxing Day although they only live 20 minutes away. We are going to DHs parents for the day.
So when do the DCs (5 and 2) get their presents from my parents? If they leave them here under the tree they won't get the pleasure of seeing them opened but at 5 and 2 they have an inkling Santa only comes to their house and not the GPs!
How do you get round this? What's the normal thing to do?
