A new study has found that mothers of babies in households with food insecurity are less likely to breastfeed exclusively for the recommended six months after birth.

The study, published Monday in the Canadian Medical Association Journal, found that half of the women who lived in households with food insecurity — inadequate or unpredictable access to food because of financial issues — stopped giving their baby only breast milk by the time the child was two months of age.

Of mothers in homes where food security was not an issue, fewer than 40 per cent stopped.
