Yes, but the baby had to be listed on the parent's passport. No way the State Depatment would do that for a baby who wasn't a citizen (as Obama would not have been had he been born overseas).

Not that I know of no. As late as the 80's; nobody ever said anything to me about listing my kid on my passport.

I know that is done now--my sister had her kids on hers. But in the earlier period, I never heard of it. I traveled all over the world and saw lots of babies and little kids.

I travelled on my mother’s passport as a child in the 1960s, but she had to have me added to her passport at the Passport Office.
