Sims 4 Twins

[Chloesauras]

Hi there!

I'm quite new to the Sims 4 and was wondering if anyone can help me?
I recently just got my sim pregnant and I want her to have twins.
I got the fertile reward from the fertile reward store but I didn't get it until after she had done a pregnancy test and found out she was going to have a baby. Will there still be more of a chance of getting twins? Or did I have to get the fertile reward before they tried for a baby?
Also is there any other way to get a better chance of getting twins?
Thank you!

Your sim will have a higher chance of twins if you get the fertile reward before pregnancy, I believe. You should definitely check out Carl's guide to pregnancy and babies in the Sims 4, if you haven't already. It's right here:http://www.carls-sims-4-guide.com/parenting/babies.php

I will check out the guide now. Thank you!

If you own the Outdoor Retreat game pack, you can concoct the Elixir of Fertility to increase your chance of having twins. If you own the Spa Day game pack, you can visit a spa for the Fertility Massage.

P.S. I'm not sure whether either method influences your Sim's odds of having twins once they've already taken a pregnancy test. Good luck!
