Results of the Bet...
I played through the rotation, and the three babies have been born.
Pregnant Sim #1, the one who already had two sons, gave birth to...another BOY. (His name is Liir, for anyone who cares.)
Pregnant Sim #2 already had five sons. This time...she had a GIRL. (Name: Frida.)
Pregnant Sim #3 was a mom to 2 daughters. She gave birth to a...BOY. (Whose name is Joker. Yes, seriously.)
Soooo...Ning wins the bet, having got all 3 out of 3! Congrats! :D You now can have a prize of your choice.
Nicole and Lala both got 2 out of 3, and David 1 out of 3. But there will be more bets in future generations, so better luck next time. ;)
ALSO: I added 7 more teenagers to the "Gen L Teens" entry, if anyone is interested.
