Can Sims have children?

If you mean Sims from EA games, yes. Two adult Sims (male and female) that love each other can have children. If you want kids have them kiss each other a lot and such and one of them will ask "Should we have a baby?" Sometimes the phone will ring and you will have a call from an adoption agency that asks if you would like to adopt. Gay/Lesbian sims can also adopt children. However, adopted children can have a different skin color than your adult sims. You will be told the babies gender and asked for a name. Make sure you feed it and sing it to sleep (sometimes sing twice) when it cries. After 3 days the baby will become a child. If you want to control what your baby looks like you can always save before it changes to a child and keep loading your family until you like the way the child looks.
