A California mom is speaking out after allegedly facing hostility for breastfeeding on a plane. Juliet Thomson was on a United Airlines flight from Salt Lake City to Los Angeles when she was reportedly told to "cover up" after nursing her 4-month-old daughter Charlie. In an interview with YouTube star JoeySalads, who has recently shifted his focus toward breastfeeding activism, Thomson said a female passenger on the plane called her "disgusting" and complained to a flight attendant.
