Hi @simplyzoe
I use TwoJeff's sim blender which shows up in build buy as a plant that can be clicked on to open up a menu one of which is to take your sims back to their longest days in their current life span so as I enjoy playing toddlers and kids you can imagine how many times that gets used-) It also has a lot of other functions such as skilling up your sims and filling motive needs so i place this plant in all my community lots where I can use it to stop all sims from stinking when they have been there a while-)
Twojeff has apparently retired which I hadn't realized but his mods can be found on the following link and if you scroll down to the simblender.zip it downloads perfectly as I have just tried it.
you will find it after clicking the build/buy miscellaneous tab where you will see a fern for $1 I think it is. this is what it looks like when clicked on in game where the menu shows up

Apologies the menu is hard to see in the picture because I could not get any closer to take the pic but to the right there is a tab entitled aging and when you clicked on will provide you with a list of choices such as age up or down by so many days or the one i use a lot is reset sim back to max days which takes whichever sim back you choose back to the maxim days of their current lifespan.
All players have their own preferences to whatever mods they use but as I tried this one first then got used to all it's other multi functions as well I chose to keep it :)
