Like any parent, you want your child to grow up healthy and happy. But unhealthy weight gain is a serious problem for many children. Being overweight can lead to serious lifelong health problems, such as diabetes. It can also hurt a child's self-esteem, lead to depression and anxiety, and cause isolation and bullying from peers. The good news is, there's a lot you can do to help them. And even if your child isn't struggling with weight, now is still a great time to teach healthy habits that will last a lifetime.
