My family has had two absolute rules when it comes to gifts to kids in the family:
1. No fingerpaints until age 8 (one of my aunts gave me finger paints when I was like 5, and they were conveniently lost for many, many years.
2. No drums. Ever.
My sister decided that my 2.25 year old nephew needed a drum set. My brother loves it. The rest of the family is deciding on the appropriate punishment for my sister.
