Would you throw green bananas in the bin?
Some are ready to eat now. Some tomorrow. And some need a few days longer.
One thing you are assured of, each of the bananas will ripen, given a little patience.
Children also develop at their own pace. Any group of boys aged 12 years will clearly demonstrate a 5 year spread in their maturation, visible in height and muscle structure.
Early maturing kids have a clear advantage in almost every sport, especially in those which include physical challenge. They are more likely to be picked for teams and matches, which builds skills and confidence and delivers a more positive sport experience. Good, right?
