You missed watching Godzilla® movies and wrestling in slow motion with your kids when they're 4 or 5? And teaching them to melt plastic army men with a magnifying glass? And giving lessons on how to approach and treat animals? A lot of fun stuff comes early on. If you wait until they are 10 you miss it.
I stand corrected.
I guess I was talking more of the family dynamics. The mother is of extreme importance in the younger years, the father is of extreme importance in the later years (see inner city for negative example).
But you're right. Wrestling in slow motion is a blast.
