The first thing to remember is that the turn doesn't worry your child very much. They are not in any pain or discomfort and as far as they are concerned they can't see what all the fuss is about. This is because when the eye is turned the brain does not pay any attention to it so your child isn't seeing double. Sometimes when a turn is first developing the child will get intermittent times of double vision but the brain learns very quickly to turn one of the pictures off. This is called suppression and if it occurs long enough then the eye that's being turned off won't function as well in terms of eyesight.
Lazy eyes are quite common in young children.
It's important for you understand that your child's eye turn is not your fault. It's nothing you did to your child that made their eye turn. There are a number of reasons why an eye may turn. As a result the treatment for each varies. Usually this type of turn is an inward eye turn.
