If a 9u softball parent would ONLY 1)play catch with their kid, and 2) buy a damn dozen wiffle balls and throw them for their kid and 3) start reading DFP, they would never have to pay for a lesson. Good luck trying to get them to do it.
In my experience and observations, the kids who have parents willing to do the work with them - ESPECIALLY at a young age - are the kids who develop higher level skills quicker, and move to TB sooner, because they have out-grown the competition level of the rec league.
Although I've been around this place since very close to when my kid started playing, and I have made a determined effort to learn everything I can to help my kid be a better ball player, I've still had to pay for private instruction. Apparently, my DD's ability to hear the words coming out of my mouth faded. Surprisingly, though, those same words spoken by a paid instructor are heard clearly.
