There will be one present at the hospital at birth, but youwill need to find one for continuing care. Babes are usually seen a week after birth by pediatrician.
That was not even something I thought about while I was pregnant with my daughter, for some strange reason. I actually went with the one that did Navia's first check ups while in the hospital because I really liked him. They also offered me a list of them just in case I didn't already have one. I don't know if all hospitals do that though.
Good luck!!
