Don;t worry about a big Xmas lunch. Cook the turkey (whatever) the night before and have turkey (etc), and cranberry sandwiches on the day - that way mum is not stuck in the kitchen, and the kids don;t have to sit through a BORING meal when they really want to play with their toys.  
      I gave our youngest two some left over rolled out icing from the Christmas cake  and food colouring pens the other day.  They spent ages drawing pictures on the icing, eating a bit and leaving some  to dry to show their Grandparents.  
Sometimes the easiest of things can keep them happy for hours :thumbup:
