I have had them once. The second birth of the 100 baby challenge I am playing. The first child was only a toddler, so my sims Parenting skills were not very advanced. So then I had a toddler and 3 babies on my hand with no help. I was almost ready to throw in the towel; between painting for money, skilling up the toddler and taking care of the babies my sim was constantly on the verge of passing out. But somehow everyone survived and none of the kids were taken away.
