Wow you guys, great job! I learn so much from you all! Lol!
I didn't know attractive and eye candy LTR would work on children! I didn't know babysitters would be beneficial so I never hired one.
I played in sunset valley and purchased a lot in front of the sea for the moodlet, so with an empty lot mom and dad went on a date to town and ended up trying for baby in the judge's chambers (city hall) and came out with a moodlet that looked like
Then I built for them not a house but a big room with an all-in-one bathroom, and both mom and dad had the wish to woo hoo in there, I save that wish for a couple of days, after the first twins were born.
An interesting thing was that mom harvested apples from the park so for the first three pregnancies she ate lots of apples, but only had girls... I don't know if apples work on fertility at all, but it seems like it, because it still beats me that after the fertility treatment they had less children, maybe because mom run out of apples, she also started having boys...
Of course best friends from childhood would be RI when teen, but I forgot Mortimer was grumpy, and Sam Sekemoto grew into a "mean spirited" Sim, so I had two teen that had a "rejected first kiss"
As hectic as this challenge may be, I also found it fun and I may try it again later, unofficially of course!
