My contacts landed on my son's phone.

I accidentally let myself log in to my son’s iPad with MY log in vs his so all my contacts and texts populated to his iPad. I can’t easily erase them. I have it correctly logged in under his apple account now but I can’t get it to erase the contacts and messages without having to do them one by one manually

Sounds like when you logged into your account on the child device, you allowed contacts to sync which means your contacts came down onto that phone. But then, when you logged out, you chose to leave contacts on the phone. Then when you added child's iCloud account to the phone you may have merged contacts. If this is the case, this shouldn't be that big a deal to solve. Keep in mind that he may have had, let's say, 20 contacts as a young child. You, as an adult, may have 1000 contacts. So that would mean after the merge, he now has 1020 contacts total. A few of his and most of the rest are yours. Sound right so far?

You are right. It's a pain to try to delete your contacts from his phone individually so there's a better way. Go to and log into HIS iCloud account. Once there, select "Contacts". There, on that web page, you'll see the 1020 combined contacts living in the cloud. From this area on the web page, you can select multiple contacts quickly and delete them. Try doing a select all. (command+a). Then,while holding down the command key, you can individually click the contacts you'd like to keep and delete the rest. In other words, using our fictional numbers from above, command+a to select 1020, then command click to unselect 20 contacts. Delete all 1000 at once. That would leave 20 contacts only. His contacts.

That should sync back to the phone and you're done. However, if you did not merge contacts early on, then there's a possibility some unwanted contacts (yours) may live under the category of "on my phone". You would see that as a group in your contacts. If that is the case, then deleting them from would not work. It can still be done. Just a few extra steps. Let me know if that's the case, and I can provide directions on how to solve that as well.
