How to add sim/s to a household via the neighborhood screen?

Hi! Its been a while since I did this but if I remember correctly if you have the sim already made and alone in a household you go to manage households via manage worlds find the household/sim you want to move into a new household and select transfer sims (the two arrow symbol at the bottom of the panel) then select the household you want to move that sim into and complete the transfer, it'll act the same way as when you ask a sim to join the household so transfer funds etc. 

Or you can add a brand new sim to an existing household by selecting it and choose edit household from the symbols at the bottom and when it all loads up into CAS you can click the add new sim next to the existing members picture icons at the bottom and start making the new sim that way. 🙂
