President Barack Obama's daughter, Malia, is now 12 years old and 5ft 9in (1.75m). But what's it like to be a young girl who's taller than the rest?
BBC Breakfast spoke to Terri McGlone, who's 16 and measures 6ft 1in (1.85m), Faith Dwight who was 5ft 10in (1.77m) by the time she was 12 and Tam Fry from the Child Growth Foundation.
