Breastfeeding is best...that's the advice most new moms get from their doctors and it's supported by strong research on the health benefits.
But now a new study out of Canada suggests there may be an issue to look out for if you breastfeed more than 12 months.
Parents of healthy children ages 1 to 6 were recruited during routine doctor visits between December 2008 and July 2011. In all, 1647 kids were included.
The team asked the mothers about their breastfeeding history then cross-referenced that information with lab tests that measured iron levels in their baby's blood.
While the average breastfeeding duration was 10 months, 27-percent of participants breastfed for more than a year.
The startling find...when breastfeeding continued past the 12 month mark, the risk of iron deficiency went up... nearly doubling.
Iron is important to a child's brain and neurological development.
The American Academy of Pediatrics recommends that doctors conduct risk assessments for iron deficiency anemia.
