Some of the best times come when your kid is old enough to understand what is going on around him or her. I once made a demonstration of how long you get to interact with a kid with quality time. I took a 72 inch string to represent the full life of your child. Then I cut about 51 inches off of it, to represent when your child becomes an adult. Then I cut off 5 more inches to represent your child getting a driver, license. On the other end, I cut off 5 inches to represent them being too young to do a lot with as a father. That left 11 inches, representing the eleven years you have a chance to have quality time with you child that can never be replaced. Those are the years you get to turn your child from a kid into an adult in the image you would like him or her to be. Only those 11 years!!
