with the new babies in the patch are they born after a sim gets pregnant?

Actually, the transition is rather sweet. The Infant floats out of the bassinet (and by the way I love the new design that comes with GT) and softly lands on the floor. Knowing myself I will likely place a mat of some sort in front of the bassinet. I really hate the thought of a baby on the floor or a rug that's been walked on. I'm very excited about Infants, and looking forward to, hopefully, being able to navigate through Growing Together. There appears to be a lot to it. Yikes. Hope my head doesn't explode. LOL
