I want to change from child account to adult account on my iPad.

I’m not entirely certain what you’re asking; whether it’s the ID itself, or the ID used that’s changing.

If you’re using the same Apple ID, and want to change the details of that ID:

• Update the birth date associated with your Apple ID - Apple Support

If you’re swapping from a child’s Apple ID to a separate adult’s Apple ID on that iPad:

• Sell, give away, or trade in your iPad - Apple Support
