How do I find who a sim's parents are?

[Beady]

I've looked all over, and have probably just missed this in-game.  Is there a way to tell who the parents of a baby is?  I have a family set up that I was working with for a day or two and then I switched to another family for a couple days.  I came back to the first family having a new baby.  Of the 3 adults in the family, only one is a parent.

I remember in Sims 2 there was a family tree type of thing but I can't seem to find anything like that.  Am I just blind or is it not there anymore?

yes the select the sim your needing to find this info out. then on the right side of your menus select the 1st tab. the area that has all your sims characteristics there is a button on it that looks like a family tree. hit it and you'll get the sims tree.

Gah, just figures.  Blind as a bat.  Now I get to figure out who knocked up my sim and beat him to within an inch of his simmy life.

Thank ya much!

edit: upon checking the family tree, only the mother shows.  Guess this kind of thing is what'll have to happen...
