I will buy 字母 flash card. As how to play with baby : I don't have solid idea as we may need to buy a book in order to understand more and to work properly. I just read the website and some BK discussion that we may need to show each card 15 times so that the baby can memorize. How big's is the card you find in book store? It need to be really big (A4 size).............
For BB 糊仔, I have same confusion. Nurse said better to start at 6th month...Can we really start at 4th month? How to start?
