I wish I knew what I did but now my daughter gets all of my text messages so there is a way. I am not getting hers, but if someone has the answer how to undo what I have done you can likely reverse it and get all of your child's messages. My daughter's friend sent her 200+ stupid messages so be careful what you wish for.
If you and your daughter share the same Apple ID and both have iMessages, she could be receiving those messages. She could also have her phone setup to make you don't see her messages on your phone though.
Which phone do you have and which phone does your daughter have?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
