You can add up to 5 children. 😸
If the child is between 14-18 years old and has an account and card issued in their name with the bank, both parents can see the "Kiddo" tab, if they request the child to log in and are authorized on the child's account.

If your child is between 8-18 years old and doesn't have a bank account in his/her own name, he/she only has a sub-account attached to your account, only the parent who gives him/her access to the app can see the "Kiddo" tab and will be able to transfer money to his/her account.
