Playing 3 or more Sims in a household, is it difficult for you too?

I have a one child per couple policy.

I remember when I first played Sims 3, one couple had 6 children, it was a nightmare trying to control them, especially when they were all young, and vowed never to allow them to have any more than one child.

So, basically, I have 6 household members max. 1 Child, 2 parents, and 2 Grandparents. Once the child grows up and gets married, usually one of the grandparents have died, and the newly weds can't have a kid until the last standing grandparent is on his/her last legs.
