Q: How do I add my child's birthday to their AppleID?

Hi deanphil,

Are your kids under 13 years old? See: Family Sharing and Apple IDs for kids

If not try to add their birthdate on the https://appleid.apple.com/ page before you try Family Sharing setup again.

But since you say they already have an Apple ID, I am not quite sure what to do about it. I just edited the post above with a second link to the My Apple ID page... maybe you can set it up there?

Hmm i guess it is something special because you created these accounts under MobileMe instead of iCloud... I'm not very sure about this topic, I would contact Apple Support (http://www.apple.com/support/appleid/) or wait until one of the forum cracks can help you;)

greetings jl

my kids are all 13 now! It was the only way I could set them up as children using their existing Apple ID, otherwise I'd have to create all new IDs.

now now that they actually allow kid accounts they should allow us to modify old accounts.
