I say if your going to have a third, have a fourth, because if you only have three, the third get's left out. And the middle has emotional problems. The first get's the new stuff, the second get's the hand me downs, and then come the third, evertything is so worn out, the third get's all new stuff. I say this, because I am one of the children out of a family that only had three. But who knows, maybe you will have kids that will be different.
