Now that I figured that out, has anybody done a teen makeover? Is the colorful hair available for teens (it's not for pre-teens). Before I either have another baby, or adopt somebody, I need to decide if I'm going to grow Dora into a teen... If she can have pink or blue hair, she'll be the teenager in my game, but I really want her to have weird hair

Seriously considering adopting, because it's faster. Can single Sims adopt? Or does one of my married couples have to adopt? Has anybody done that yet?
Thanks in advance!
