Does your child enjoy the flash cards more than the mashed potatoes? Obviously, yes! You flashed his first five favorite words five seconds per session, three times a day for five days. And he already knows most of them (or even all!). Good job, congrats! You have mastered the art of flashing cards and your kid has made successful entry into the ocean of knowledge. 
Now that both of you are ready and compliant for this method, let us make it REALLY professional and FUN. From now on, you may increase the number of cards flashed. Make another set of five cards. The words would, of course, be the ones that would hold his joy and attention. Now, flash the first set of five words, followed by this new second set of five cards. This way, you would be flashing ten cards - that would take ten seconds - three times a day. And the following day, include another set of five words that would thrill him. So that works up to 5 + 5 + 5 = 15 cards. That would take as many seconds for you to flash them to your child. Does it sound strange that this simple and regular flashing could make your baby read? Please carry on, the results are awesome - you will see it for yourself! As you keep flashing these fifteen cards with a cheerful disposition, your child would briskly capture them all as pictures in his mind. Remember to shuffle the cards and to change the order of flashing. Day after day, watch some amazing facts: As his eyes are gradually ‘trained’ to stamp the words in his mind,
- his observation improves,
- his urge to be restless and hyperactive is satiated with ‘challenges’ thrown to him on seconds-basis,
- he basks in your love and proximity.
And you, in turn, treat yourself watching your little one blossom. yes, flash card-time is celebration time. 
As the cards are flashed regularly with all your love and enthusiasm, excitement and speed, the child will be able to identify several of them by the tenth session. It is now time to remove the known card from that set (”retire the card” is what we would be saying for this process from now on.) Instead, introduce a new card to that set of cards and continue flashing. By this way, your child will be reading nearly thirty cards in three weeks. It is now time for you to help him link the words to frame sentences. When your child has learnt to read the cards, introduce cards that would form a sentence that he would himself be saying happily. For example, “I love to play with my red ball.” or “Mommy takes me to the park on Sundays.” : that would mean eight cards for each sentence. But as the card “to” is used in them both, we will need only fifteen cards for two sentences and not sixteen! Thus, as your child gets used to reading the flash cards, you will, in fact be preparing fewer new cards than the number of words in the next sentence. As the words grow all the more familiar, your child would be found reading them all at any and every given opportunity: in the newspaper headlines, television news flashes, the huge billboards and hoardings alongside the roads - these are all so very catchy, you know! And your child will be thoroughly excited! Or is it that you become more excited and thrilled? A difficult question, indeed!
To keep up with his amazing learning speed, you may always carry some fresh flash cards and the wide-tipped pen with you. As and when his attention is drawn to some interesting item, just draw a card out, write it down and flash it to him. You will add this card to the regular list of cards that you are flashing currently. This system is most suited for a broad age group - 9 months to 4 years. Then how to know if a 9 month old “knows” the card? Well, after about fifteen sessions of flashing, spread five of the fifteen cards before him. Now simply call out a card. Watch him move forward and bang his hand on the correct card. he might even attempt to pick it up and proudly show it to you. He is already a LITTLE GENIUS, in his own way!
