from my point of view, memory map is more effective for older age.
As for 6 mths, actually the mother can teach ownself. These brain materials are available in United Square in front of Cold Storage exit Basement. Invest on those materials which emphasize level by level and according to age group.
1 set cost about $500-$1000 (all levels).
Don't buy those cheap cheap from popular bookshop. They don't have the spiral progress.
Over the weekend, went to United Square to rackie, hey, that was a good recommendation u know? I thought those brain stimulation materials are not commonly found here.
BTW, care to share about how a typical Shichida lesson is run? I haven't got Shichida parents around, and have heard so much that is a good program.... Are the materials used in the lesson unique to them?...how does it compare to the one sold at United Sq.?
