I have no mods, no CC installed. This is a brand new game. I'm playing three brothers, my version of the Sims 2 Curious brothers. Pascal is in the medical career, Vidcund in science, and Lazlo is a programmer.
Pascal was abducted first, his labor & delivery went as it normally should in the hospital. I had him check in at the front desk, he made his way to the surgery room, and within a few minutes, his daughter was born. No problems encountered.
Vidcund was the second abduction of the household. I had problems with him giving birth at the hospital. Vidcund went into labor a couple of minutes before Pascal was supposed to leave for his daily job at the hospital. I send Vidcund alone. The doctor stood at the curb and did not move, even after Vidcund checked in. Pascal showed up at the hospital around this time to begin his shift. Although the red heart symbol appeared above Vidcund's head, he never walked to the surgery room. He just stood there, so I sent him home. The game seemed still broken, so I clicked on Pascal, and the only option I had was to also "send home." Once I did that, I finally got the loading screen again to go back to the house.
Now back on the home lot, Vidcund was the only one there. Pascal was still "at work," Lazlo off on his daily job, and Pascal's daughter at school. I sent Vidcund back to the hospital to have his child. This time, it did not show Pascal there at the hospital. But Vidcund immediately walked to the surgery room, didn't have to check in at all, and the doctor who had been standing on the curb the previous time was already at the surgery controls. Vidcund's daughter was born within minutes and I sent them home.
I don't know if it was the doctor that was broken, or Pascal's work shift at the hospital causing issues.
