What do you do with your baby's hong baos? Spend, deposit into an account for baby, deposit into your account and keep a record, or another method?

I just deposit into their bank saving account. Now as my daugther is older, I teach her how to do money management. Since chinese new year is over I counted all the ang bao money that she has received and set aside a portion (10%) for her to buy food/cake/toys that she likes and the rest I bring her go to bank together to deposit in and show her money is growing in bank book.
