My little sister is 4' 11" and is 11 years old. she just weighed and measured herself today so she got on the scale and it said "74 pounds". when she got off she came up to me and said "am I underweight? Am I unhealthy? Will people look at me and think I'm underfed?" I felt so bad so I'm asking you guys since I have no clue. She is the sweetest thing and she's just picky! She doesn't mean to be skinny on purpose!

Im afraid so, after reading this I went to a online BMI calculator which is Body Mass Index and typed in her weight and height and it showed she's underweight..

Really? Oh I hope she'll be okay! I mean, she's always full of energy and immature and silly. She's probably fine.
