You will know that you have already hit your growth spurt if you are at least 21 years of age.
If you are 14 and experience a growth spurt at 12.5 years old, it is possible you will hit another growth spurt. If you are 5'6, it is possible you will gain several more inches.
Once you are 21 years of age, then know that this is one sure sign of a growth spurt.
13
You have a growth spurt before puberty when you are age 7-9. And you will have your next growth spurt during puberty, usually age 13-15.
Yes you can. it depends on how much he's eating and drinking milk. Those help in the line of growth spurt. On average, kids usually hit it a around 14, 15 but still you can hit one at around 12, or 13 so it all depends.
no
11-13 most likely
If hitting a growth spurt at 13 and already 166 cm then it is possibly that you can get to 175 cm. You should hit another growth spurt in a few months.
Everyone is different.

Pretty much everyone will have a growth spurt during their childhood , mostly between the age of 11-16 depends on the person.
