How Do You Manage Your Population?

When I use mccc I set it so the couples can have kids and pair up guys and gals both have babies doesn't matter to me and I have it check only a few days so they aren't overrun. When I don't use mods I may pick a few families at random to mix in with my main family and those will be switched out with other families or the rotation will get an add on leaving most families alone unless I'd really like a random couple to have more kids. Sometimes I may choose families I've shared and not played or gallery sims just to have someone else whichever I'm in the mood for. That said I only sometimes take pity and do makeovers.
