The change in air pressure in an aircraft during take off and landing can alter the balance of a person’s ears and require them to “reset” the balance through opening their jaw or yawning. This is second nature to an adult, but babies do not yet know how to do this.
Instead they feel a lot of pain — they scream.
A quick way to subvert this situation is to coax your baby into opening and closing their jaw through feeding. If you breast or bottle feed a baby during the take off and landing phases of an air journey, the change in air pressure has a limited effect on an infant’s ears, they are able to reset the balance naturally without feeling discomfort.
