Alright thanks ladies! I thought about that this morning and got a little worried!
Baby is covered under mom for the first thirty days. Once baby is born call your insurance to add them on right away since it can sometimes take a couple weeks. They cannot add baby before they are born since they need the full name and birth date.
Usually babies have the insurance when they are born. I'd suggest you call your insurance and ask them about it.
Usually they make exceptions for new babies or family members and you get to add them right away regardless of when open enrollment is. But you should get in contact with your insurance company and make sure. Just call the customer service number on your insurance card.
