2. Open a custodial account (< 10 years old)

A custodial account is owned by your child, but managed by your before they are 18 years old. Make sure don't put too much money into the account so even your child loses all the money, it won't make any big difference to your and their lives.
3. Apply for a debit card (< 13 years old)
