I use Motherlode a lot because I get most of my apartments/houses from the gallery and I need my families to actually be able to move into them immediately. :D I give them their money boost so they can afford the house I want for them.
Since I play with large families a lot, in order to be able to do special events without having to worry about them, I'll disable their needs so I can get through the event and do everything I want to do and not have to keep track of everyone's needs and worry about someone starving or whatnot.
Similarly, I often spam toddlers through the ball pit to get their movement to level 4 in one sim day. As such, I use Make Happy to constantly fill their needs over and over so they don't get exhausted or hungry and need to stop.
