An Aussie mum has sparked a debate online after revealing she got into a row with another passenger after she boarded a business class flight with her one-year-old baby. Charlotte Heinrich was flying business class to Singapore with her baby boy when a disgruntled passenger confronted her about his crying. The mum-of-two recalled the ordeal in a video posted to her Instagram page on Wednesday, captioned: “Should mothers with babies be allowed to fly business class?” “Had she not in her past life travelled with one of those kids and experienced a crying baby before?” “I guarantee every mother with a crying child is trying everything she can to soothe their child.”
