The worst thing about some of this is these days so many of us are stuck leaving our kids with day care/school so much of the time, and plenty of these "professionals", don't get this stuff.
Day care here ran about $2k/month and the education level of the teachers was just not up to par for that amount of money. I always wondered where the money was going, they all had college degrees but got paid 1/2 or less what public teachers do in this area. There was a ton of bragging from management at the day care about how great the academic start was (this chain even brags about higher SAT scores!) and I think it was mostly hogwash. I was always thinking someone was making a lot of money on the day cares as it was not hard to figure out their approximate gross revenue/month. So often the day care was making things worse... take one step forward at home and 2 steps back at day care.
Thankfully my child is in public school now, we have a great school system, and the teachers are a million times better at dealing with this stuff in productive ways.
