I was on a redeye about five years back where there was a screaming kid about six rows ahead of us. He screamed for about fifteen minutes when the mother got up and moved him away from the rest of the family. Unfortunately, it was right behind us. He screamed and kicked the seat behind us for what seemed like an hour. I couldn't take it anymore and spoke to the FA who had the parents move him back to their own isle.
Talk about the epitome of rude parents with children on a plane!
