How do you have kids on the sims 3 mobile?

In sims3 for 3DS, you cannot have a baby :-(.

But!You can woo hoo (sex). This will not lead to a baby, but it will lead to a good time. What you can do if you want a family is go to CREATE A TOWNIE in the Main Menu. If you want your child to be like you, just create them. Give them your last name so you can have some type of family relation. Get friendly with them. When you get friendly enough, there is an icon that says "Move In?" Click it. After you click it and the other sim says yes, they will move in with you and your partner, or just you.

This is the only way for you to have a family. Also, this helps you with big bucks because if you have three people working, you get more money. So thats the good of having a full grown family.
