I like it. I enjoy the whole experience of. Including time jumps through the pregnancy and after childbirth, and time jumps till the kids have grown some.
They can just work time jumps into their story. Not every story has to take place day 1, day 2, day 3, day 4. I write campaigns and backgrounds for D&D and sometimes I time jump years. As far as the renders go, i know some will hate this, but you just limit who can get pregnant.
I quoted a joke from one and then my daughter asked me what I was talking about. I almost explained it and then thought, "wait. This is probably not appropriate."
