For small infants, I would test vision by showing them a rattle and having them follow it as I move it from side to side, up and down and in a diagonal pattern. For hearing, I would shake it on one side of their head to see if the baby turns toward the sound. If they’re not turning, that may be an indication that they should have their hearing examined. Parents should also observe whether their child is responding to different levels of sound. If there is a history of frequent ear infections and a concern of hearing loss, an audiological evaluation should be considered.
