@feruze-- Both my children went to schools who use the Reggio Emilia approach to curriculum and I highly recommend it. It does cost more than regular preschools but if you don't want to send your child to a traditional kindergarten or preschool, you will have to pay more regardless of what kind it is. But if cost is an issue, you might want to do your research and speak to the schools about it before making a decision.
When I first signed up my older son to a Reggio Emilia schools, I wasn't really sure what we were getting into. But the school gives parents many opportunities to take part in activities. And since parents make up part of the council who makes decisions for the schools program and curriculum, it didn't take long for me and my son to adapt. My younger daughter also went to the same preschool.
