Just met a couple that had kids in the late 60’s. They had twins......doctors never saw it coming. I can only imagine.
My mom kept telling the doctor she was carrying an octopus. But back in those days, all they did was listen for heartbeats, and there was only 1 detected. Sure enough, mom went into very early labor and after I was born, they saw my sister’s feet! We were really tiny, 4.2 & 3.8 and my sister had some lung issues, but we survived and thrived. The Dr. claimed there was one sac and a shared placenta,but that’s doubtful because we are clearly not identical, I look native American and she is all Irish!
