My younger set are 7, 4 and 2. The 7 year old is asking for more expensive things now (nintendo ds) and the 2 year old really couldn't care. What we do is the kids each get one big present from Santa, then have a certain number of presents under the tree each, usually around 5. If the 'big" present uses up most of their budget - well they will get $5 gifts under the tree LOL but I try to have them the same number of gifts, but spend about the same amount.
