| 1Formula supplementation is defined as supplementation of breast milk with formula (with or without other supplementary liquids or solids) among infants breastfed at the age specified (2 days, 3 months, or 6 months).

| Note:The sample size was insufficient to present estimates by sociodemographic or geographic characteristics for the 1999 births. Similarly, data on exclusive breastfeeding and formula supplementation were available on too few of children born in 2003 to enable sociodemographic or geographic breakdowns (survey methods). | ||||||||
