Since my husband is 1/2 Japanese we really wanted our daughters to learn both the languages of their heritage, especially since my husband regrets that he didn't. Imagine my excitment at finding Bilingual Baby Japanese! It is more than the 30 minutes minimum, and total immersion for that 30 minutes plus, that experts recommend-plus it visually holds their attention. I really like the fact that they take the words used and then put them into a sentence. I am also pleased to say that I have learned alot of Japanese too!!
