my son is 3 and my daughter will only be about 2 months old at Christmas, I'm planning on getting her 2 or 3 small gifts like new baby toys or a stuffed animal because Santa comes. my problem is that I got my son that elf on the shelf thing when he was born so he has one, do I get my daughter one too? should it be a Christmas gift or should it show up on Dec 1st like my son's?
