This year unfortunately it will just be us and MIL. DHs sister and family can't get up to visit as they usually do.
Unfortunately can't visit my own family as MIL will be left on her own.
Meaning my DC won't see any of their cousins or other kids over the hoildays which they love at Christmas. 
Any ideas how to make it special for them regardless? DS is 11 and isn't into Santa and pantos anymore and ds is 6.
