Gifts?

I have a 2.5 year old and a 12 year old. All judgements aside... how many Christmas gifts for each seem like enough? Ok I am not talking about like really expensive gifts either. Just toys normal things. I want the boys to have a nice Xmas display of gifts when they wake up Christmas morning but am not sure how many presents will be enough? And I know some will say that the amount shouldn’t matter etc etc. I know this. But am wondering how many gifts y’all end up buying for your kids?
