Small or Large families?

Small families, because large ones just over extend me. I have one family that accidentally had twins, then their cat gave birth to a kitten. Plus, the dad had recently adopted a dog. So now it's 2 parents, 2 kids, 3 animals, and it's just wayyyyyyyy too much. It's hard to keep the animals fed and happy while also training toddlers and keeping the parents from stressing to death.
