During takeoffs and landings, changes in air pressure can cause popping or pain in the ears. Kids are particularly vulnerable due to their smaller ear canals, which can trap air and allow pressure to build. To avoid earaches, keep babies awake during ascent and descent, even if this means waking them from a nap. Give younger children a bottle or pacifier to help alleviate pressure, and supply older kids with gum, snacks or drinks. Even making funny faces and talking to your kids can reduce the risk of ear pain. If your child is prone to earaches, a dose of Children's Tylenol prior to takeoff may help, but check with your doctor first just in case.
