re: How hard is the jump from one child to two?

Two is harder, for sure. But the second child is usually much easier than the first, because we don't have the time to indulge it as much. I can tell you from experience that two is about as hard as it gets. We had four. A toddler and an infant is tough; it really doesn't make it harder that there are a couple of older kids hanging about. They actually help entertain the toddler.
