54 kg I am 13 and weigh about 8 stone
yes it is healthy for a 5 foot 6 thirteen year old.
Around 6 stone?
The plural form of thirteen year-old is thirteen year-olds.
about 90 lbs
it dipense on how tall you are
Of course.
you should be from the weight just over 7 stone to about 10 stone
12 stone is already too heavy for a 13 year old. Do not put on more weight.
No way I'm 12 and I'm 7 and 1/2. My 13 year old friend who is slim is 9 stone. IF anything you are light! :-)
I'd say it's a good weight because I'm 12 and I weigh 7 stone
A thirteen year old is considered a teenager, not a kid.
