Sims 4: make newborns optional / remove newborns from the game

@lauriekirsty_xx luckily you can just age them up. I only leave them newborn for a day if my Sims give birth. Or you can adopt from infant age and by doing that you can skip having a newborn. I usually adopt.

As the infant life stage was only recently added I don't imagine it would be changed now. It's quite a big change to the game mechanics.

I prefer the infant life stage over the newborn one though as you can do more with them and interact more with them too.
