Hi!
My baby was born at late August 2008. I tried to teach her by flash cards when she was around 6 months old. Maybe she cannot move very good at this time, it seems quite sucess. Around 10 months old, she can chose right answer between two choices after I flashed for 2 or 3 days. However, when she was around 1 yewar old, she always take the cards
, so I stopped flashcards teaching.
