My child can send iMessage to my contacts

I just set up my 7 year old's iPod up with Family Sharing. I set it up for her to have her own apple ID and iCloud account. None of my contacts are listed in her contacts, but when she does to send an iMessage and starts entering the recipient's name my contacts begin to populate. She is actually able to send an iMessage to my contacts.

I verified that her iMessage is setup with her account and not mine.

Anyone know how to make sure my contacts are available to her?

Thanks!
