ha ha I don't think I have them living in a ley line, twin trait lot... although I have not checked. If your Sims is taken care of well, and is an a good mood the whole pregnancy, she will often have twins. An old cheat is to eat cheesecake before trying for a baby, that will make twins too!

The highchair is a pain. That's why I don't use it. I am glad they allow us to feed them from the counters now. The game used to make us teach them how to walk, and talk, now they learn as they grow :)
