The chain is available in the box immediately after birth, babies' retinas are not fully developed. a newborn's retina can only detect light and darkness, or very strong contrasts (high contrast) between black and white. The black and white images seen by the baby in the first six months send very important visual signals to the brain through your baby's retina. These powerful signals are very important in terms of increasing your baby's brain development and speeding up visual development. after the third month, red is added between black and white as a visual stimulant. in studies conducted around the world, it has been observed that brain development accelerated as a result of increased visual stimulation in babies who were allowed to see high-contrast objects in the first 6 months. my q baby first cards are specially prepared for babies between 0-6 months. and it is recommended to use it from the 3rd month when your baby starts eye tracking. our set includes a total of 20 thick cardboard cards and 40 consecutive black-white and red illustrations. all pictures have been specially prepared to be contrasts of each other. it must be used in the order indicated on the cards. it is not recommended to use alternating order. it is hung on the baby's stroller or cradle as they can be seen by attaching it to the hanging loops in the boxes through the holes on the cards. and the front side hangs for 1 day and the other side for 1 day. the same process is repeated until all cards are finished. While the cards are on the hanger, you can talk to your baby about the cards. However, it should not be forgotten that the important factor here is that the baby can follow the contrasts in the picture with his eyes during the day, rather than understanding what the picture on the card is, and that his brain is stimulated as a result of this follow-up. our cards will not have the desired level of positive effect in hand impressions at irregular intervals and in indefinite periods, except for the specified time and order.
