hi my son is 2yr old his weight is 17kg, I know he is over weight.. can this be an issue later?

A. hi dear During this second year of life, growth slows down. Your toddler may gain about 5 pounds (2.27 kg) and grow about 4 or 5 inches (10 to 12 cm). By 2 years, children have reached about half of their adult height and 90% of adult head size.
