An estimated 16 percent of U.S. children are overweight and carry a significant risk of developing heart disease and diabetes while young adults.

One study in 2005 by scientists shows that formula fed babies who gained weight rapidly during their first week of life were significantly more likely to be overweight decades later.

"It suggests that there may be a critical period in that first week during which the body's physiology may be programmed to develop chronic disease throughout life," said Dr. Nicolas Stettler, a pediatric nutrition specialist at The Children's Hospital of Philadelphia.

And so he thought that the findings pointed toward ways to prevent the development of long term obesity. More studies need to be done to be sure.

The American Association of Pediatrics recommends exclusive breastfeeding during a baby's first six months of life," Stettler said. Breast fed babies are less likely to be overweight.

Some other benefits of breastfeeding for infants are:

• Fewer ear and respiratory infections.
• Less allergies.
• Reduced incidences of cancer.
• Certain immunities are passed from mother to child.
• Reduced incidence of blood infections and meningitis.
• More contact with mother.
• Reduced incidences of insulin-dependent diabetes.
• Acts as first brain food as it helps to set down the proper matrix for humans.

Pretty important benefits, don't you think? So encourage new mothers to breastfeed. It may seem inconvenient, and may take some getting used to, but the benefits to the baby may last a lifetime.
