My sis and myself have sent our girls to Shichida classes and we do see the effect of right brain training. We in fact met Professor Shichida last week when he came to S'pore and learnt a lot on how to nurture your kids. I think you should find out more on this forum:
www.sgparenting.com on both Shichida and Glenn Doman Methods. Exposing my girl to Shichida Method is the best thing I can do for her. It's worth the money and hardwork!
What would be the best age to send the kids for Shichida classess then?
