I think all of us moms and dads here still experience the "ready for action" vs. "I want to hide and cry" days. I"m having one of the hide and cry days myself, today. It doesn't matter how long we do this, it never changes. There is SO much to be SO happy and about, and then so much that can't even be described with words.
But, you are so right, in the end, we have our children. OUr wonderful, beautiful, strong and feisty, PERFECT children. Congratulations on figuring that out already! All the best to you!
