My daughter blinks eyes for 3 to 5 seconds and during that time if we call here name she doesn't listen anybody. Seems like she got lost for those 3 to 5 seconds. She started doing this since 1 and half year. Now from few months frequency of blink is very very frequent like some she blinks after an hour or two. But earlier it was very rear. We have recorded the video of her , but there's no option to upload here for video. Because photos will not work for proper diagnosis.
