Insurance question

Am I supposed to put baby on my insurance before she’s born? I was under the impression that was something I was supposed to do after the birth with her ss# and birth date, but I’m filling out my hospital pre-registration and it asks for the baby’s insurance information.

I had Medicaid with my first so this is new to me.
