To age up children there is a process, using Grim's Core, which has always worked correctly for me. I posted about how to do it in this thread: http://www.modthesims.info/showthread.php?t=496731 (I hope this helps.)

I glanced through responses/replies and have not seen any that mentioned a big problem with using this mod, IF one is playing the Wait for it Legendary Trait Ambition. What using this mod during that Ambition is NOT reward the Sim a legendary trait after their legendary quest is completed successfully. This happened to my knight, so I tried to just give him the trait he did not receive using Debug option, but that helped the score in the game not at all. The game did not count it, so I thought it was a glitch, as my game has ended abruptly before, so I continued on with the Legendary Ambition, and the Dragon of Ever Moor quest showed up for my monarch, as its the only option for the monarch to get a Legendary trait, I played it, and thank the gods I saved right before his final entrance into the cave to defeat the dragon, and yet again no trait was rewarded, so I quit the game, and rebooted the game, tried again, and again, no trait was rewarded. So I thought for a moment, recalled I had added this mod, as it does help relieve those awful sims with nasty behaviors of those bad behaviors, so on the 3rd time, I decided to remove the mod, and played again from the same point, and what do you know? My monarch got his trait, and it was counted by the game. Thank goodness the first failure was not the kings, or I would have to begin it again with an old save, as my knight can just so the Fountain quest in order to get his trait and be counted. Anything less than Platinum is unacceptable in my kingdoms! LOL
So folks, if you are playing the Legendary Trait Ambition and are using this mod, remember to take it out before playing, or you might not get the traits your sims are trying to earn. And remember also that giving them the legendary traits using debug, has no effect on the games score of legendary traits completed, no bearing at all, as it will not be counted. So taking the mod out during this ambition is the only course.

I can't seem to get this to work on windows 8 (I have the ultimate fix to run Pirates and Nobles). I've used this mod before, so I know I'm not doing anything wrong. Any suggestions? Thanks!

there's a problem like i remember in some mod i'm not sure it it was a dynamic professions or Grim's Medieval Core there was a mod through that mod you could create a big family for example king+great builider is his brother and etc please i really need i had that mod before a disk format ;( and lost everything especially with mods and i'm asking it

First, I apologize for my English (isn't my native language).
I've a question:
My Monarch married a doctor (both heroes created), they had a daughter, but as she didn't age (I know children don't age), so I used a Mod for her to become an adult and continued as a princess. She was very beautiful and I wanted to marry her to another hero, a knight. I turned her into a Playable Sim, but the problem is that she doesn't do anything at all (since she doesn't have a profession) and consequently doesn't interact with many objects, just the basic ones like cooking things (this is when I transfer items from the inventory or buy in the village and market).
I just wish I could play with an adult princess who "isn't" a monarch (because I like to occasionally play with her father (current monarch). Is there anything I can do with her using this Mod?
I welcome any idea to make her more active. I also can't click on it while it's active, meaning I can only click on it with other active Sims.
Thank you all for your attention and help/idea and thank you also to the creators, for making our games cooler. (=^_^=)

I know the comment is old, but in case anyone else has the same problem, maybe this will help:
I did the same and my monarch's daughter was also small with an adult head and a little disfigured, but I read elsewhere that if you "save as" (so you don't lose the game if it goes wrong), exit the game and come back, she will be a normal adult and very beautiful. I tested this and it worked for me.
However..., read my comment above about my experience with her.

I want to edit my post and comments concerning this mod, and the Legendary (wait for it) Trait Ambition from 5 posts upwards from this one. I said the game will not give a legendary reward to a sim during this ambition while this mod is installed. I also said trying to manually set a legendary trait onto your sim who was not rewarded the trait during their quest would not be counted by the game.
While it is true that the legendary trait will not be rewarded to your sim after their quest is at its end, I have experienced just two days ago now, that using Grim's Core Debug Menu during any time in any quest to add a Legendary trait to a sim does work, and is counted by the game, and the ambition with TZ Dynamics installed. If anyone decides to attempt the ambition with this mod installed, if and when you try to add the unrewarded legendary trait to your sim manually. use the option in Grim's Core NOT the option in TZ Dynamic's professions mod. The wording for each option is different, where this mod's option says "change" legendary trait, when the sim doesn't have one yet, so does fail in being counted, but in Grim's Core Interactions Debug menu option it says "set" a legendary trait, so using this option has worked for me, then I just turned off the debug menu enabled option by unchecking it in the main game options menu, so it is disabled, and play out most of the game just using TZ Dynamics mod. Since Grim's Core debug menu is so overloaded, I cannot bear using it for a longer time other than to use its options for a specific event to take place, like for example to triplets baby basket before any of my hero sims produce more than two children, since using this afore mentioned option makes it possible to continue keeping more children in sims household instead of making them leave every time a new infant is born. It has no limit, so a sims household can have a million kids in it, if you so desire, and if you can find the room! LOL
I just couldn't bear playing the game without my sims having extra abilities of other professions, as I have played using this mod for so long that I cannot even fathom my sims without the added profession abilities I gave them since first using this mod, so glad I am to have discovered that Grim's Core option to grant Legendary Traits works just fine, so I can still have TZ Dynamics profession mod installed, and not fail the Legendary (wait for it) Trait ambition.
