Parent phone data is on daughters phone after daughter phone was erased. Connected to I tunes to restore, now moms photos texts show up on daughter phone. How to disconnect data between 2 phones that don’t want to share?!

by trying to restore a child’s phone that had been disabled; a parent connected said phone to parent Mac book air.

Child phone is erased, parent info is now stored and continues to be shared on child phone.

-child’s contacts and photos are wiped out.

how do we get parent info, including shared texts disconnected from child phone but keep parent data intact ?!

thanks:)
