Your Baby's 22nd Week of Life

Safety Alert

In some parts of the country, beets, carrots, collard greens and turnips contain large amounts of nitrates, which can cause a type of anemia, according to the American Academy of Pediatrics. Because you can't test the vegetables in your area yourself, and because baby food companies take precautions not to use vegetables high in nitrates, it is safest to buy commercially prepared jars of these vegetables.

Fact of the Week

In the January 1999 issue of the The American Journal of Public Health it was reported that babies fed only breastmilk had significantly less risk for infectious illness than their nonbreastfed peers. Researchers studied 7,092 mothers and infants in the U.S., looking at the relationship between frequency of breastfeeding and infant illness. Exclusively breastfed babies were found less likely to develop diarrhea, vomiting, coughing and wheezing during the first six months of life. The passive immunity appeared to be "dose-related." When other foods were added to an infant's diet in addition to breastmilk, passive immunity was reduced, depending on the frequency of supplemental feeds. "Intense and perhaps exclusive nursing may be required to attain significant protection against infectious illnesses," according to the study.
