Q: My son is 6 years old weighing 28 kg has developed a slight tummy. Is he normal or is this the case of obesity? Moreover, two of his teeth had already fallen at the age of 5.5 years. He also has a grey hair. Please advise me.

A:He is slightly overweight, improve his eating habits, try to avoid junk food and induce him into more physical exercise. Falling of two teeth at 5.5 years of age and one grey hair is not a problem.
