FFF, yes to the magic tree. I have the magic tree as well, and it takes up permanent residence in every one of my sims' houses.
I have a hack that allows for individual sim aging, so aging can be turned off for only certain sims. That's what I use when I ban a sim from growing old so I can torture them forever. I don't know if the magic tree has the option to turn off aging for sims, since I use that hack instead.
I would kill myself if I had permanent toddlers. They drive me insane when they can't really feed themselves. (Bottles everywhere!) But a few hacks I have make it slightly easier.
I like teenagers instead. I'm not sure why.
I'm on MSN only by request these days, so just ask for me to be on and I will at the next opportunity. That does give me time to load more screenshots.
