My 4.0 honor roll student

Jayden has gotten perfect grades all year long and I am wanting to compensate her for doing so great. She has two seperate savings account, one that Josh & I contribute to every month that will be used for college. Then she opened one for herself and she is saving for a car for when she is 16. I feel like I would want to put the money I gave her into one of the accounts rather than handing her money and having it get wasted at Target. Anyway I am still uncertain what I want to do so I was wondering if you could tell me things you do for your kids or things your parents did for you.
