Since this post the game has decided my own Sims should invite my other Sims to their birthday parties but I have aging off for all my played Sims. So, it's a wasted invite as I have to remember to say no. And for the life of me I don't understand how my Sims have their babies when aging is off, (when playing a different household) the 'baby' wouldn't be growing or getting any older, ready to be born if aging is off for played Sims. It still irks me. Because it literally makes no sense if you have aging off for all played households their 'baby' ages enough to be born. No sense... None at all.
