Emily Norcross: I held my legs together when he was trying to be born.
Lavinia Dickinson: Mom, What are you talking about ?
Emily Norcross: Because I was scared and your father wasn't home. So, I held my legs together a bit too long to keep him in there. I think now that may have been a mistake.
Why was holding him for a bit long a mistake? What is she trying to point out?
