If you press the pause button and then go into edit mode (both in order is important), then you can delete the cradle/bed. That way the sim is able to interact with other sims or object while in labor, and give birth later.

I did know, I just wasn't bothered cause I was only really taking the photos at the time.

Also as a side note, a glitch can occur if in labour on a non-home, non community lot.
It's happened a few times now, but i'm not sure what triggers it. If you choose the "have baby at hospital" option, sometimes they just start walking... and never stop.
Not sure what causes this exactly, as it's only sometimes.
But yeah, thought i'd warn y'all bout that. The game is really buggy atmo.
