How do you know if your baby is responding to infant stimulation flashcards?

I’ve read a little about stimulation of infant vision with black and white shapes. The downloadable cards by brillkids look really good.

How do you know when your child can see the cards or is responding to the stimulation? When do you then switch them over to words?

You can tell that they are responding by watching your baby with the cards. You will see them looking at them and really not turning away from them.

With changing over to words. I waited until Sophia was 3 months old. I started her on YBCR then because I new she could see bigger things because she was looking at bigger things. She would notice the letters of her name on her bedroom door. It is lots of little things that give it away when they can see more things.

So observe your infant closely and you will know when they are ready.

You can also check their vision by how well they can track an image.

Hold a B&W image up and see if they can follow it with their eyes.

The stimulation cards aren’t supposed to be used like regular flash cards. Babies aren’t supposed to learn anything from them, but rather, be stimulated. You can place them around their changing table and crib to look at, or on the floor during tummy time. You want to put them anywhere the baby is spending a lot of time. You can also show the cards to your baby as often as you like, for as long as the baby will look at them. Like Kimba said, you can move them around to help with visual tracking. Your baby will be able to see them, even when first born, as long as you have them close enough to his/her face. The baby will look at them; they are very interesting to babies!

It is recommended you show them until 4 months before moving onto regular flash cards.

Are infant simulation cards supposed to help stimulate the visual pathway and also neural connections?
Glen Doman talks about using bits of intelligence cards - eg. triangle on 15x15 card and showing it 10 times a day and saying ‘triangle’ when holding it infront of the infant for a period of time.

Thanks for the help!
