Sims 4 MOD by java7nerd
Pregnancy Scan Determine Gender and Number of Babies by java7nerd at Mod The Sims
This mod is an independent script and should be compatible with other pregnancy-related mods, such as MasterDinadan’s “Longer/Shorter Pregnancy Length”, scumbumbo’s “Pregnancy Terminator Command Mod”, and AgonistAgent’s “Babies for Everyone!”.
If you are at the lot limit for number of Sims: e.g. 7 Sims with one pregnant, you will only be able to have a single baby. The mod may give inconsistent outputs if Sims join or leave the household during the pregnancy as the game may reduce the number of babies to avoid exceeding the household limit of 7!
