All you really need to do is to feed them and take care of them. Babies grow up into toddlers on their own. If you're trying to get it to happen RIGHT NOW...sorry, that can't be done.
On the iPod, they do not grow up past the toddler age
you get a birth day cake make him blow out the candles and if he still doesn't grow click on him and it should say grow up click on that and he should grow up.
Sometimes
No.
Yeh. They'll grow into a kid after a few Sim days. But they won't grow to an adult after that.
First if there is any question about your toddler you need to consult the babys Doctor. Than being said a toddler could be having night terrors ,still something to be brought up to the Doctor.
No, your baby doesn't grow up, the farthest it can go is a toddler and it can learn to walk.
earth has so many humans because people have bays and the babys grow up and then tthey have babys,etc,etc
The baby will grow into a child but never an adult. You can't make her/him grow up but (s)he should take about 3 days sim time. Id you hold down the R1 button it will speed time up, but other than that nothing will speed it up. --JBiebzx :D
It takes about a week (in sim time)
No, they grow from a baby into a toddler and then they can't age anymore than that.
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.
