Is it wrong if..

Am I being unreasonable if I don’t want my SD’s BM to EVER hold my baby and ask my husband to enforce this

Reasoning: I don’t like BM. I want something for myself and I don’t want her hands on my baby. I understand that she didn’t ask for me to be in her child’s life, but idk. And lastly, there’s no reason for it. I don’t think she needs to be part of my child’s life.
