Well if a 9-year-old is 50 pounds he would look very thin he would look like he has not eaten in 2 months but if you can't control it he should go to the doctor he would be 13 or 14 pounds from the average when he turns 10 he would be 20 pounds from the average and that's all that I know but really not good If a 9-year-old is 50 pounds super unhealthy.
But 13 year olds should weigh about 95-120 pounds.
If you're 13 and you weigh 50 pounds, you must be skinny boned, and you might want to gain more weight.
So, no it's not normal.
But it's okay.
As long as you're not fat. Well, consider this: How tall are you? Did your doctor say you were healthy? Do you eat the correct foods? Do you exercise often? P.S. - there is no "normal" or ideal weight for anyones age.
This all depends on how tall they are. For example, it is much healthier for someone who is 4'6'' to be 50 pounds than someone who is 5'6'' to be 50 lbs. More likely than not, (and this is just a guess, it is by no mean 100% accurate or not) most 12-year-olds are within maybe 3 or 4 inches of 5 feet. So they should be within about 10 pounds either under or over 100 lbs, respectively towards their height. If you are still worried or unsure, ask a doctor. They can probably answer all of your questions and help you with any conderns you may have.
Talk to your doctor they can give you the range for your height and weight!! See the Related Link for "height/weight chart" to the bottom for the answer.
