I do not want to let my mum hold the baby.
What's going to happen to the baby if your mum holds it?
I'm not going to let her hold my son. I don't trust her.
You should let your mother hold your baby. This is an important time in your family and a good chance to bond.
My mum just wants to hold a baby since she is a grandmother but she never liked me anyway. She was a bad mom.
It's cruel not to let your mum hold your baby, there's no harm in it. Whatever problem you have with her, sort them out by talking to her in a civil manner.
