I cringe when I see those types of parents. It is the child's journey, not the parents.
On a bright sunny day in the summer I sit back & enjoy the atmosphere. I feel bad for the families who seem to miss out on appreciating the moments. Strike out or laser beam double, it is his path, not mine.
I also think it is funny that parents pay for great coaches to coach their kids on travel teams but then think they should coach the kid, too. The travel team director for my son's team (and who he goes to for hitting lessons) played several years in the minor leagues and had some iconic all time greats as teammates & coaches. He then went on to be a college coach before starting the travel program. He has truly forgotten way more about Baseball than I have ever known. It would be just the complete height of ego, cluelessness & crassness for me to think I should coach my kid from the stands...
