There is never a weight your "suppose" to weigh. If you can tell me your height I would be able to tell you a healthy weight for the average 12 year old person to weigh.
Around 70-85
If you are 4'7 and are an 8 year old girl you should weigh 60 lbs.
about as much as 90-105 pounds
Depends..........
20
an average nine year old boy's weight is about 75 to 90 pounds
You have to be 65 pounds through 85 pounds. That's like a normal 10 year old weight. I'm 10 and I'm 80 pounds.
Find it out on a bmi index,
there is no perfect weight for a 12 year old girl... it depends on how tall you are. puberty also plays a dramatic role in weight and height
you should weight at lest 102
it depends on how much they eat
