How do I disable my child’s Apple Pay

Hi uetta225,

Thank you for posting in Apple Support Communities! Assuming you and your child are part of a Family Sharing group where you are the organizer, you can lock Apple Cash for your child by going into the Wallet app on your iPhone, select your Apple Cash > Tap more ( ... ), scroll down and tap on your Childs account and select "Lock Apple Cash". This will preferment Child from being able to send or receive using Apple Pay.

Check out more information here: View and limit your child or teen's Apple Cash activity

Hope that helps!
