This answer is only from my knowledge, i did not get a PHD in science so please don't rely 100% on my advice. My son who is 15 weighs 100 pounds. So i`m pretty sure that 75 pounds for a 9 year old is fine. i recommend to get the 9 year old's bones X-Rayed or get a blood test. i`m late 9 and i`m 60 pounds but i`m a male. i`m sure 75 pounds is fine most people i meet are about 10 to 9 pounds heavier than me.
