Smoking Affects Mother's Milk

Wednesday, 29 October 2008 12:29

Mothers who both smoke and breast-feed expose their infants to tobacco smoke in greater concentrations than those who do not smoke or those who smoke and bottle-feed.  A study of 330 mother-infant pairs found that breast-fed infants of smoking mothers have urine cotinine (a nicotine derivative) levels 10-fold higher than those whose mothers do not smoke.  The study concluded that health care providers need to be as diligent in encouraging mothers not to smoke after birth as in the prenatal period.
