My son needs to lose weight?

Do not buy sweets or anything unhealthy anymore, I know this will be extremely difficult for you and your family but your son is too young to control his cravings yet. Since he does not understand the bad things about being obese he must be taught. The entire family will have to work at this diet and exercise thing with him. This is dire to his health. I understand that he is your baby boy but he needs to gain control of his weight and early in life. I hope this helps, some exercise you could do is try to introduce him to more fun sports, swimming also!
