My daughter receives my texts and vice versa?

I have an iPhone 6s and my daughter had an iPhone 4. Recently, I bought her the new iPhone 7. At the Apple store, the employees told me to enter an iCloud account into the iPhone 7. Since, she didn't have an account, I entered mine. Once we got home, we found out that she could see my texts and vice versa because we had the same id. I want to give her privacy, so I made her a new account. She entered that new account into her phone. But, we can still see each other's texts. I think that might be because her phone was set with my account so it doesn't change. I want to let her restart her phone with her own account, but I don't know how.

If you are not confident in doing this then your best option is to return to the Apple store and have them sort it out for you the way they should have done in the first place.

To do this ideally you'll need to know all your Apple IDs and passwords, and both you and your daughter along with the phones should visit at the same time! Dig around in settings. You both have something checked that you get each other's texts. Happened to us. I did not want to hear from DH fantasy baseball league, and he did not want to see texts from my flute students. Check under Send and Receive and also Forwarding. Easy.
