To give birth to twins or even triplets, here are a few cheats that may work, but it really depends on the game. The first two have worked for me pretty well.
there is also a hack you can download called an Inteenimater, type it into Google and some sites should come up with the hack.

On the Sims 2 if you want your sim to have twins,just type in the cheat boxforcetwinsand when your sim gives birth she will have twins!!|Warning: I think this cheat only works on macs
Yes, you can have twins on any of the sims games. Oh wait, if you are talking about ps2? No you can't. PC you can tho, or mac or whatever.
You can not even have babies in the PS2 game so how can you force twins
