Should I intro flash card to my baby? Does it really help? Some articles claim that the ability of photographic memory (right brain) is temporary. As they get older the left brain will develop gradually. It is better to bond with kids with others activities to have less-stressful atmosphere. And it might have conflict as right and left brain manage different skills' sector. Right brain mostly art and left brain mostly numbers, languages. Right brain should not override. Any parents here can prove that flash cards can help develop the child's cognitive development? thanks.
