How do you have a baby in Sims 3 ambitions?

Answer 1

first u must be married to the person of opposite sex

but YOU MUST HAVE A COT before u can have a baby

then you must soften him up with romantic actions like "hot smooch" or "flirt"

after you do that a few times, scroll down on romantic actions and click "try for a baby"

ur sim will either be successful or not successful with a baby

the baby should arrive in about a day or so

Answer 2

Make sure your Sims are both at least a young adult and that they have a good romantic relationship. You have to choose a bunch of romantic things to say or do to another Sim. More and more buttons will pop up in the 'Romantic' chat category when talking to your Sim. Keep on doing it until the Sim you are talking about finds you 'extremely irresistible' and then the button will finally come up to 'Try For Baby'.
