Twins I have only had one set of twins and mine were identical! Both were boys. So its possible. Do you guys know if you can have more then just twins?
The limit is only two babies. I have a hard time managing two at once, let alone imagining what more would be like
There is a hack at modthesims2 that allows triplets and quadruplets. When it's time to give birth, they ask if you want a random number of babies, if you want to choose how many babies, or if you want the original number of babies (which would only be 1 or 2). I randomly got quads once, and let me tell you, it's NOT easy.
