Is there a way for you to make your sims grow up very quickly?

yes there is such cheat!
Get the cheat box up by pressing Ctrl+Shift+c at the same time
then type in ...
Boolprop Testingcheatsenabled true
(make sure all the capitals are added in) Then hold shift and click on the sim and click on set to birthday. It will then make your sim grow up!!!
Hope this helps.

Yes there is. Just Put in the boolprop testingcheatsenabled true cheat in, and then press shift click on the sim that you want to grow up and select set age. And the set to birthday. After you do that you buy a birthday cake and them blow out the candles and then you will be grown up. I do this all the time so I know this works.

There sure is! I use it all the time. To get your sim pregnant, start by typing in "boolprop testingcheatsenabled true" in the cheat prompt. Shift-click your sim, click Spawn>tombstone of l&d. Click on the tombstone and then click on "get pregnant with..." and select your child's other parent. Once the sim is pregnant, click the tombstone again and select "speed up my pregancy".

You may have to click "more" to access some of these commands i've mentioned. Then your sim's stomach will start to poke out and she/he will give birth about an hour or two later(sims time). Once you've named your kid(s) and all that stuff, and your parent is holding the baby in his/her arms, shift-click the BABY and select "Make Selectable". This will make your baby's picture dissapear from the list of family sims. Shift-click the baby again and click "Make Selectable".

Now you can tell the infant what to do! Remember in the past you couldn't even select a baby sim. Now shift click the infant and click "set to birthday". You may want to max it's aspiration so it grows up better (set aspiration will be on the shift-click menu). Next you click (NOT SHIFT-CLICK) the baby and click "grow up". Select the parent holding the infant and tell them to put the baby down. They will pick the baby back up to "help with birthday". Now that your sim has grown into a toddler it's a lot easier for you. If you want your sim (age toddler or higher) to grow up no matter their age, just shift-click the sim and click "set to birthday" then click the sim and say "grow up". I know these are a LOT of instructions all together but they go very quickly and I can turn my infant into an adult in less than TWO minutes! Enjoy!

Yes there is. Type in boolProp Testingcheatsenabled true and right click on your sim then click on set to birthday. Their aging bar will go right to the end and you can have a birthday party or whatever to make them gro up.

The correct way is- boolProp Testingcheatsenabled true.(with the spaces) Then when you click on things you have to hold down shift. Hope you helped.

Or, instead of having to set to birhtday and go through all of that, you can just type in"boolProp Testingcheatsenabled true". (without the quotes) Then make sure you're the sim you want to get older, hold down shift and click on them. A lo of options should come up, spawn. Then another list comes up,select "Tombstone of L and D." A gravestone should appear. Click on it and select Age Transition.

P.S. This also does a lot of other stuff too. Hope I helped.

Okay so I did every thing you said but it won't work at all I am so bad please HELP!!!!!!!!!!!!!!!!!!!!!!!

Yes. All you need to do is hold shift and click on a sim. Hit "set to birthday". It will give them a boost but not completely age them. Click on the sim WITHOUT holding shift and hit "grow up"
