Pregnant

In Sims 2 female Sims can become pregnant when they "Try for Baby" with a male sim. Have both Sims relax on a double bed. When their relationship is high enough, the options "Woo hoo" or "Try for Baby" will appear. "Woo Hoo" is actually the same action but the female sim will not get pregnant.

But it is also possible for a male sim to become pregnant if he is abducted by Aliens! The pregnancies are the same for each gender, though.

The pregnancy lasts 3 Simdays. On the first day the female might throw up quite a bit. On the second day the first so called "Baby Bump" will show. Mostly it is at this day, when the needs of the pregnant sim suddenly go down much faster than normal. On the third day there will be the second "Baby Bump", and from there on it will not take much longer until finally the baby arrives. Also there is the possibility of twins being born, which is but a rather uncommon occasion.

If your Sim has a job they will be put on maternity leave until the baby is born and they also get three additional days to stay home from work.
