How early can you start Glen Doman programme for babies. I heard you could start as early as 2 months. Is that true?

My PD said you can start as early as 1 week. :) To make the math cards you need to get 250 gsm paper and cut it into 11x11 inch and you can buy the red dots from popular. The dots should be 19mm. They sell it in packs of 100. After that laminate the cards. It took me about 1 week to do the 100 math flashcards - from no 1 - 100.
