I'm a teacher and, based on my experience at the school I work at,  fdk, as it is presently constituted, is indeed nothing more than extremely overpriced daycare. "Discovery/play based learning" is a sham. Grade 1 teachers are very frustrated. The fdk students they welcome have few if any of the basic readiness skills necessary to learn and progress. 

Lastly, should the government keep these ill considered fdk policies in place, the least that they can do is replace the fdk teacher with another ece. You don't need someone with 6 years of university to supervise kids on a play structure.
