How many sims do you usually play with in a home?

Any more than 5 and my sim icons at the bottom of the screen get stupidly tiny I can't see them well enough to click on them, so more than 5 just isnt an option in TS4 :( I know I can change the screen resolution, but then the rest of my game doesnt look right. So, I usually end up with either 2 parents, 2 children and a pet, or 2 parents and 3 children. Nightmare if 1 of the pregnancies turns out to be twins or triplets! :#
