Well for one of mine I am in a sticky situation. I made a vampire and had her advance in mixology and cooking and she already maxed both of them. I had her marry William Fangman and withing a few hours she was pregnant. The problem is that William is handsome, but his features were passed down to their little baby girl. Needless to say, this toddler looks like something out of the black lagoon. I'm debating whether or not to keep this file since the mom has maxed out my two favorite skills, but her baby scares me.
My other non-documented file is basically a guinea pig file for generations. (I just got it yesterday) I have two sims who are currently enjoying the water slide, shower woohoo, and tree house woohoo. They just had a little girl named Ruby and I am currently waiting for her IF to arrive.
