Give your toddler a cup of juice or a lollipop during takeoff and landing. Swallowing helps to prevent ear pressure from building up.
Give your child small snacks such as fruit snacks or dry cereal throughout the flight. Chewing and swallowing can ward off painful ear popping that occurs during a flight--especially during unexpected turbulence, which can cause a drop in cabin pressure and subsequent ear popping.
Give your toddler an antihistamine prior to the flight if he is especially prone to ear sensitivity. Antihistamines act as a sedative, which may help your child sleep through the plane. Antihistamines are also known for reducing ear pain caused by changes in cabin pressure.
