5  In 2008, 71.3 percent of women with children were in the labor force.  ~12 million of the 19 million US children under the age of 5 are in some form of child care.  Pre-school aged children average ≥35 hrs/week in child care settings. 5

6  Breastfeeding rates were significantly lower among infants who attended child care at 6 months. (Li 2005).  Infants in child care before 3 mo were 42% less likely to have been breastfed (Kim 2008).  Compared with children who had no child care arrangement, children who attended child care were breastfed for shorter durations (Benjamin 2009). 6

8  To examine the impact of child care provider’s (CCP’s) breastfeeding support on breastfeeding duration 8

9  Largest US longitudinal study of mother- infant pairs  ~4900 pregnant women 18+ participated  Questionnaires completed almost monthly  3rd trimester through 1 yr postpartum 9

10  Mothers ≥ 18 years of age when recruited  Singleton infant  Birth weight ≥ 5 pounds  Full term or near-term infants  Mother and infant healthy at birth  Infant has no long term medical condition that would affect feeding 10

11 Breastfeeding duration <<12 mo vs. ≥12 mo <<6 mo vs. ≥6 mo 11

12 1. Feed a mother’s pumped breast milk to her baby? 2. Allow mothers to breastfeed at the child care place before or after work? 3. Allow mothers to come in and breastfeed during their lunch or other breaks? 4. Thaw and prepare bottles of pumped milk if needed? 5. Keep extra breast milk in a freezer for use if they run out during the day? 12 At 3, 6, 9 and 12 months

13  Individual CCP’s support over time:  Yes=Breastfeeding supported by CCP in at least one survey  No=Breastfeeding not supported by CCP in any survey  Cumulative breastfeeding support over time: # of “yes” answers X 100% # of valid answers (Yes or No)  Low breastfeeding support : <33.3%  Medium breastfeeding support: 33.3 to 66.6%  High breastfeeding support: >66.6% 13

14 Mother  Age, race, ethnicity  Education  Household income  Marital status  Breastfeeding Intention  Workplace supports breastfeeding 14 Infant  Sex  WIC Participant  Parity  Age when mother returned to work  Age when infants were first cared outside their home

15  Bivariate Analysis:  Chi-square  T-test  Multiple Logistic Regression  Adjusted for all covariates 15

27 Breastfeeding duration <<12 mo vs. ≥12 mo <<6 mo vs. ≥6 mo 27

28  Sample is not nationally representative  All data are reported by the mother  Child care support only represents the perceptions of mothers 28

29  Largest longitudinal study on infant feeding  Extensive questionnaire development  Short recall period  Relatively high response rate over time  Sample is well distributed throughout the US  Detailed data collection allows to control for a large range of confounding factors 29

30  Mothers with CCP’s support to feed pumped milk were 2.3 times more likely to breastfeed ≥12 months.  Mothers of infants with high CCP’s breastfeeding support throughout the 1 st year were about 4 times more likely to breastfeed ≥12 months than those mothers with low CCP’s support  Multiple supports at the CCP are needed to improve breastfeeding duration 30

31  More research is needed on child care provider supports and breastfeeding  Standards for the state to regulate breastfeeding support at child care facilities  Implementation guidance 31
