How can you have kids on Sims 3?

You can have a child in Sims 3 by having a husband or romantic interest. Then you have to have to option in 'Romantic' saying Try For Baby. Then both you and the other Sim will go up to a double bed and it's the same with 'Woohoo' except your Sim will become pregnant with this option after a few days. You will know that your Sim is pregnant because it will say that 'you might want to keep your Sim near a bathroom - from unknown causes' After that, you just have to have patience and then a couple of days after that your Sim will be giving birth. You can choose to have the birth at your current location or at the hospital.

Hint* If you want the baby to be a girl - eat more watermelons

If you want the baby to be a boy - eat more Apples

Hope this helps xx
