T.D.
When my daughter was very young I always had Santa bring lots of gifts. But I changed that when she was a little older because there were times that grandma/grandpa or aunt/uncles would end up buying so many gifts it seemed like mom and dad are the only people not giving many gifts.
Now Santa brings one special gift (or sometimes a few if accesories are needed for the main gift). My daughter may pay more attention to the details than most kids but she has always realized how many presents come from mom and dad.
