First Christmas, mil bought dd exactly the same presents as Santa - because she WAS Santa in her opinion. 
We told her that this would confuse dd. Santa delivers to our house and she could get something else. We gave her a heap of ideas. Last Christmas, mil bought an unbelievable amount of toys and clothes. Then complained that our house looked too full and dd had been spoiled.
Mil has just dropped off this years pressies. I worried when they took 2 cars to drop things off...
She has just told DH that she couldn't resist buying the Entire "Happy Land" range of ELC. WTAF!
She must have spent a fortune. I know I sound ungrateful. However, I just think this is insane. We now can't move for presents. We (Santa) are getting dd a balance bike and 2 Julia Donaldson books. Mil says she has to get dd lots of presents as we don't give her enough.
Argh!
