I can't join my sims to the hospital.

If my sim is in labor and I click on "have baby at hospital", there comes no option to join my sim. She just go to the hospital, have the baby and return than home with the baby. In the past I could go with my sim to the hospital and have the baby there, but no I can't do that anymore.

Ps. I have no packs, except for "my first pet stuff" and "romantic garden". I have mods and CC, but before I those had, I could also not join my sims to the hospital.

I don't speak very good English, so if there are spelling mistakes, I'm sorry.
