Did you know that mothers produce different breast milk for boys and girls? Scientists continue to make new discoveries like this one about the specific beneficial qualities of breast milk to babies from nutritional to immunological, emotional, psychological, and intellectual.
"...researchers are finally beginning to get a better handle on exactly what makes breast milk unique and beneficial," says Denise Mann, WebMD Health News.
Human breast milk contains ingredients, as well as functions, that artificial formulas cannot replicate.
Breast Milk is Tailored to the Infant or Young ChildBreast milk is not only different from formula, it's different from mother to mother. The relationship between mother and baby goes further than frequency and duration of nursing, or supply and demand. Interaction between mother and child affects the composition of milk according to the child's specific needs.
Different Milk for Preemies, Infants, and ToddlersPreterm babies receive different milk than toddlers, says Barbara Holmes, a lactation specialist at New York University Langone Medical Center.
Different Milk for Boys and GirlsAccording to a new article in Nature (Dec 23/30), breast milk produced for boys contains more protein and fat than breast milk produced for girls.
“We know that boys grow faster than girls, and perhaps this is due to the milk, or the milk may be responding to the commands of the child,” said Ginna Wall, coordinator of lactation services at University of Washington Medical Center in Seattle.
Breast Milk Protects Against Allergies and InfectionBreast milk is rich in human milk oligosaccharides (HMOs), which protect infants against infection. Some mothers have up to 200 different HMOs in their milk.
Antibody concentration in breast milk increases when the mother and baby are exposed to germs. About 80 percent of the cells in breast milk are macrophages, which kill bacteria, fungi, and viruses.
New studies show that breast milk affects gene expression in the stomach cells of infants, which could lower breastfed babies' risks of developing food allergies.
Promoting and Sustaining Adequate Milk SupplySome moms worry about having enough milk, but Gwen Marshall, a Washington state breastfeeding expert, said the reason babies don’t get enough milk is that they don’t have enough access to the breast.
According to Norma Torres' in her August 25 Othello Outlook article, "Breast feeding is more than just food, it's a buffet." She detailed the many ways breast milk changes to meet a baby's changing needs.
For example, breast milk re-formulates at every feeding to match the baby's present nutritional needs.
In addition to nutritional and immunological benefits, the closeness and skin-to-skin contact of breastfeeding provides psychological benefits to the mother and baby.
As an added benefit, breast milk tastes slightly like what the mother has eaten, so baby will likely enjoy the same foods in the future. That means less picky-eater syndrome.
