Joseph Tidd is not an ordinary boy. The 21-month-old has a congenital condition that led him to be born without a fully formed left arm. “Symbrachydactyl is the condition. He was born this way. Found out at 18 weeks pregnant, but it happened around the 4-week mark before most people know they are pregnant. When we first found out, we were so heartbroken thinking, ‘What did I do to cause this?’ Even though it was not something we did,” Joseph’s mother told Bored Panda.
