Children are usually fine. Let me be more specific. Babies. Babies are often a problem on flights. Often it’s because of the cabin pressure hurting their ears because of their under developed eustachian tubes. All babies? no. But a lot of them. Learn how to help manage the child’s ear pain if you must bring them. Otherwise, you’re just being mean to your baby.
As for your plenty of people / heart not bleeding comment. Nice to meet you, Karen.
