I have a three year old. Those of you that are parents will probably sympathize with me.

Everyone has heard of the terrible twos. When my son was two, all of the sudden the rule changed: "If you think two is bad, just wait for three." How reassuring. Insert new baby brother here and now we have an emotional rollercoaster in a child who is too short to safely ride.

Fortunately, there haven't been very many comments about four. Unfortunately, the joy of four will be lost among the chaos of another two.

This must be why parents strive so hard to be grandparents.
