You must have 10,000 lifetime reward points from completing lifetime wishes or just by playing the game and keeping your sim happy.
Buy fertility treatment with lifetime happiness points to have a higher chance of conceiving twins or triplets. Triplets are the maximum amount of babies you can have at one time
When you gain enough lifetime rewards points, you can purchase the upgrade.
If your sim is pregnant, they have a chance of twins although it is not very likely they will. However if you save up enough lifetimee hapiness points you can buy a fertility treatment. It increases your chance of twins and triplets! this does work sometimes as on of my people was a rockstar the got married and got pregnant.
Yes you can now! You have to have the sims3, by itself, you WILL have to buy the sims3 pets, which you can get from gaming sites, the best one is The Sims3.com. :)
No
Assuming you mean Triplets, or three children at the same time- yes, you can! This can either be done by surrounding your pregnant sim with children's objects and having her watch children's television (for rather long intervals). Or, if she has enough Lifetime Happiness, she can "buy" the Fertility Treatment Reward- which will increase her chances.

Marijuana is not known to be a fertility treatment at all. In fact there are studies suggesting that it causes fertility issues.
You can buy the CD from a shop or you can buy from the internet and download .
You can not turn off the fertility treatment, once you have it, you have it.
To have more than one baby at a time on Sims 3, you have to buy the fertility treatment. A lot of people say you have to eat certain things to have triplets on the game, but all I did was buy the fertility treatment, made a baby, and I had a set of female triplets. It's not as confusing as many people say it is.
You would have to buy sims 3 World Adventures.
