Breast vs Bottle and tummy upset in babies
A study of 154 mothers and babies in Guadalajara, Mexico, found that babies who are mainly breastfed for the first six months of life were less likely to have gastrointestinal (GI) problems than those babies that were mainly formula-fed (18% versus 33%). The bad news is that they also have more likelihood of having iron deficiency, putting them at risk of anemia. If the mothers had high iron stores, the babies were at less risk; unfortunately, 28% of Mexican women have low iron stores and anemia.
One of the researchers pointed out that prior studies have found that "breastfed babies don't become anemic if their cords are not cut too soon." Delaying the cut for as little as two minutes can help improve the baby's iron status and confer other benefits.
