My twins are 4.5 months old. We have not shown them any flash card for vision stimulation. I want to know whether we can start the same now? If yes, are there different cards monthwise?

A. U Actually introduced flashcards and all only after the age of 1 1/2 years not before that prior to that it is no use of giving any of these things to the child is going up naturally let it be the same way just go ahead with giving all these educational toys flash cards after the age of 1 1/2 years
