Can a baby weigh 9 stone at birth?

No, a baby cannot weigh 9 stone at birth. Nine stone is equivalent to 126 pounds (approximately 57 kg), which far exceeds the typical birth weight range. Most newborns weigh between 5.5 to 10 pounds (about 2.5 to 4.5 kg). A birth weight of 9 stone would be medically impossible and indicative of severe health issues.
