take care of them and do not let the mean girl take your baby.
Real answer (LGE edit) - you can make them age up (baby-to-toddler, toddler-to-child, etc), by buying a birthday cake, and having the sim you want to age blow out the candles. The cake in in buy mode - misc/party.
stretch it or sit on it
Go to were you can buy your awards and there will be a time box, buy it.
You pull up the cheat menu and type in: boolprop testingcheatsenabled true. then you shift and click on your sims and it should say make birthday. Then your sims will grow up! (hopefully, i did it and it worked)
Babies take three sim days to mature into children, and they don't get any older.
You can't make them go faster.
No, tomatoes do not make your breasts grow faster.
Speed up the game
you can't make your hair grow faster just let it grow
The child's hair should grow faster if you trim it but you can't make it grow faster
I am not sure about sims2 castaway but to make your hair grow in the sims2 open for business you go to a store and buy hair cream.Or go to the salon at let them but cream in your hair.
to make your flowers grow faster, you need to be a moshimember
I don't really know the answer to that. My Sims is a heart breaker and I wanted her to have lots of kids but it takes to long. I guess the answer has to be... That in Sims 3 you can't make your Sim have a baby faster. You can in Sims 2 though!
