Usually after 8 or 9 days of being a child.
turn him into a plant sim then cheat him to a kid.
Around eight Sim days.
Every certain amount of time your Sim will go on to a next developmnet stage. First you have baby Sims. Aging will eventually turn the baby an infant. After infant comes child. After child comes teen. After teen comes young adult. After young adult comes adult. After adult comes elder. After elder comes death. This does not happen in like 2 days, and you can change the settings of the game in order that the sim's life cycle is of 90, 180, or 270 Sim-days. If you turn aging off, babies stay babies, infants stay infants, children stay children,etc.
It takes three Sim days for the baby to turn into a child.
On the Sims 3 for Wii, you cannot buy Expansion packs, so unfortunately you're unable to turn your sims into Vampires, or anything on the PC Expansion pack, Surpernatural (werewolf, zombie, wizard/witch, fairy, vampire, ghost) or the genie. Your Sim can turn into a Child, Teen, Adult, or Elder, so it can age up. Sorry!
You can't, so turn them into young adults first It doesn't want irresponsible parents ;)
The homework will be in the child's inventory. Click on it and the popup will be either "do homework", "get help from" if there is an adult in the house, or "do homework with" if there is another child the same age in the house (child or teen).
If you mean on Sims 2 then you have to have the University expansion pack, then make a teen Sim go to college and they will turn into a young adult Sim. If it's on Sims 3, then I am not sure, sorry.
A teen sim cannot have a baby, but they can woohoo. I think they can accidently get pregnant, but im not sure.
You can't reverse ageing, even with cheats, but you can turn aging off in the options screen, sorry man :(
Well, it depends. In Create a Sim you can choose to be a toddler, child, teen, young adult, adult or elder. But you can only choose a teen, child or toddler if you've made atleast a young adult.
A teen Sim on the game certainly can get grounded. This game simulates real life to a certain specified degree.
