Benjamin Mayo, writing for 9 to 5 Mac:

Apple has announced that users can no longer setup iTunes Allowances for kids from today, ahead of a complete shutdown of the iTunes Allowances program on May 25th, 2016. […]

Now that iTunes Allowances is going away, families will instead have to migrate to Family Sharing. Family Sharing includes features like Ask To Buy, which requires parental permission when a child tries to buy an app or game. It isn’t a complete replacement, however, as it is a manual process unlike the automatic credit system that was iTunes Allowances.

I’m glad there’s an option available to users who relied on iTunes Allowances, but it’s a real bummer that parents will have to manually approve each purchase. Maybe an allowance-based system will return in a future iteration of Family Sharing.
