Fortunately, it's very scientific, because when I bought Coco Lion, I agreed with their idea of teaching on a monthly basis. I'm not saying that this kind of early education is not advanced abroad. The most important thing is that this month's early education corresponds to the child's ability to exercise the most every month, and the teaching AIDS and educational progress match it. If I say it myself, of course I don't know which month the baby is suitable for teaching, but the cocoa lion is systematic, phased and scientific.
