California in-hospital infant feeding practices are monitored using data collected by the Newborn Screening (NBS) Program. All non-military hospitals providing maternity services are required to complete the Newborn Screening Test Form. In addition to tracking genetic diseases and metabolic disorders, the NBS program gathers data on all infant feedings from birth to time of specimen collection, usually 24 to 48 hours since birth. The Maternal, Child and Adolescent Health Program staff analyze these data and publish breastfeeding rates by hospital, county and the State.
Please note: the data presented below should not be compared to data published in prior years as there has been a change in the methodology for computing these rates.
