You just can't do that.
You can use a cheat to make a teenager Sim pregnant, but it is not possible at all, even not in a adult sim to have quadruplets.
A lullaby will play if the Sim is pregnant, they also get little thought bubbles with a pacifier and a question mark in it.
Well, when i use a placeholder sim it's usually for a story or a sims challenge. in most cases the "Placeholder" is just there because you can't have a sim without being related to an adult sim. so for instance, you make a female teen and her mom, and then you make a male teen but you don't want them to be siblings. you can make a placeholder sim be the male teen's parent so he is not related in anyway to the female teen.
A teen sim cannot have a baby, but they can woohoo. I think they can accidently get pregnant, but im not sure.
A teen Sim on the game certainly can get grounded. This game simulates real life to a certain specified degree.
i used a pacifier on the young kid who wouldn't stop screaming!

no
No, they cannot.
You should always check the pacifier for cracks, tears and any other signs of use. Once you see that, you should definitely replace it.
