A viral video has been shared by Gloria McIntosh, a mother in Ohio, showing her 10-year-old son, Mason, who stood up at 3am to comfort his 18-month-old brother, Greyson, so he could sleep. The video was captured by McIntosh on the baby monitor in the nursery of her six children and shows Mason's willingness to stay with his brother for nearly 30 minutes. McIntosh said she always tells her kids that the true test of a person's character is what they do when no one is around, a lesson that Mason took to heart. While parenting is not his responsibility, the fact that he understood that he is his brother's keeper is appreciated.
