Very easy!
You make a male and a female and you put them relax on the same bed. Just if they are married or enganged you can do that...stay on one of them and click on the other and then "try for a baby" This is but you can make twins just if you write the cheat (ctrl+shift+c) then write twinzr2cute when the woman makes them and after the two lovers finished the "try for a baby".

Can only have twins but the cheat is forcetwins
It can happen by chance or you can use a cheat: SHIFT+CONTROL+C, then type forcetwins. My sims used the cheat once, then the second time they still had twins so be careful, because the guy can have a gene thing, that makes him have twins.
on the sims 2 for the ps2 no you can't
sorry but no
Yes, you can. My Sims just had their first set of twins and they are different sexes.
Unfortunately you can't have triplets on the Sims 2, although you can have twins using force twins.
