The timeline of raising triplets goes something like this, in my experience: The early months of having triplets blurs by. You have no sleep, you know you've had coffee, because you are awake, but you can't remember if you ate. You hear kids crying, even when kids aren't crying; and even when they aren't with you. Year one is fun, but it is still lots of work. Its like those first years of college, where you are suddenly being challenged in all kinds of new ways, but its all so fun and exciting that who cares. Its like, well raising Gremlins. By year two , the novelty has worn off. This is the time when those kids that couldn't handle the excitement of college have dropped out. But there isn't any dropping out of parenting. And there is a reason they call it the Terrible Twos - at this age parenting is more like managing a baseball team full of ... um, interesting personalities. And then you hit three years old, and it gets hard...
We tried for one, and we ended up with a bushel of fun.
