Can I switch between child accounts on ipad

Hello satava129,

Welcome to Apple Support Communities!

We understand from your question that you want to switch between Apple ID's on an iPad. We can certainly help you with this!

You are only able to sign into one Apple ID at a time on an Apple device.

Here's an article that will help you with restrictions on the iPad. You can also set up family sharing as well.

We hope this is able to resolve your issue. If you have any more questions or this does not resolve your issue, please reach back out on the thread!

Cheers.

When changing to the new ID, there may be some data loss, but you can minimize it. If syncing photos with iCloud, ensure Optimization is turned off in Settings/Your Name/iCloud/Photos and/or in Photos/Preferences/iCloud. Then make sure full resolution photos are on the device/computer. When signing out of iCloud, if asked whether you want to retain data, choose yes. Messages conversations will be lost if they are addressed to the ID. See the article below for other places that the old ID should be removed. See Winston Churchill's response in the below discussion. If possible, also set up Family Sharing  between the IDs to keep access to your apps/purchases.
