Breastfeeding has been associated with higher IQs and other measures of cognitive and developmental abilities, but the studies were often dismissed because breastfeeding and IQs also parallel social, cultural and occupational differences. In other words, who's to say that breastfeeding made Johnny smarter when it could have been that his parents were also better educated and wealthier than Jimmy's and therefore they could have provided other advantages to increase his scholastic performance.

A too tight attachment of the tongue to the floor of the mouth can interfere with breastfeeding or the ability to suck on any nipple. A cleft palate or a small jaw can also create problems, but at least a tongue tie can be relieved by a quick, easy procedure clipping the attachment, called the frenulum. These babies often are unable to touch the roof of their mouth with their tongues or they don't extend beyond the gum line. The tongue can even have an abnormal shape.

Breastmilk contains protein, fat, carbohydrates, calcium, iron, vitamins, and the other minerals. Yet surprisingly, the average mom’s diet has very little impact on her breastmilk or the baby (except for vitamins).The baby generally will not suffer if his mother doesn't have enough protein or iron, for example. He will receive all he needs unless the mother is experiencing a critical shortage.

The idea of a daily dietary requirement is easily understandable. Basically, an individual at a particular age needs to eat a certain amount of some food or nutrient for his needs and keep a slight bit for storage. Additionally, the requirements for infants, children, and teens include what is necessary for growth; and those for pregnant and lactating women have an amount added for what they are sharing with their babies. If everything that a person eats is absorbed, then 100 percent of the nutrient is available and usable.

An Institute of Medicine 2011 report1 showed that 20% of 2-5 year-olds are overweight or obese (over the ninety-seventh percentile for age). That’s an amazing 1 in every 5 children that age, an increase from 1 in 20 (5%) in 1980. And before that, over 10 percent of those under 2 are already overweight.
