Insights
Breastfeeding is linked to cognitive development, but this association is primarily due to supportive parenting and maternal education, not the feeding practice itself. Promoting positive parenting behaviors is key for child cognitive development.
Area of Science:
- Child Development
- Pediatrics
- Public Health
Background:
- Breastfeeding is often associated with improved cognitive development in children.
- The mechanisms underlying this association require further investigation.
Purpose of the Study:
- To examine the relationship between infant feeding practices and cognitive development.
- To determine if parenting behaviors and maternal education explain the link between breastfeeding and cognitive outcomes.
Main Methods:
- Utilized a nationally representative longitudinal survey of early childhood (N = 7500).
- Assessed breastfeeding, introduction of solid foods, bottle-feeding practices, and cognitive development.
- Explored the mediating roles of parenting behaviors and maternal education.
Main Results:
- Predominant breastfeeding for 3+ months showed a positive association with reading skills, mediated by supportive parenting and maternal education.
- Little to no relationship was found between infant feeding practices and cognitive development in children of less-educated mothers.
- Daily reading and sensitive parenting were significant predictors of math and reading readiness.
Conclusions:
- Encouraging breastfeeding to promote school readiness may not be the most effective strategy.
- Promoting positive parenting behaviors is a more direct and effective approach for enhancing child cognitive development, particularly for disadvantaged children.
Objective:
To explain why breastfeeding is associated with children's cognitive development.
Study Design:
By using a nationally representative longitudinal survey of early childhood (N = 7500), we examined how breastfeeding practices, the early introduction of solid foods, and putting an infant to bed with a bottle were associated with cognitive development across early childhood. We also explored whether this link can be explained by parenting behaviors and maternal education.
Results:
There is a positive relationship between predominant breastfeeding for 3 months or more and child reading skills, but this link is the result of cognitively supportive parenting behaviors and greater levels of education among women who predominantly breastfed. We found little-to-no relationship between infant feeding practices and the cognitive development of children with less-educated mothers. Instead, reading to a child every day and being sensitive to a child's development were significant predictors of math and reading readiness outcomes.
Conclusions:
Although breastfeeding has important benefits in other settings, the encouragement of breastfeeding to promote school readiness does not appear to be a key intervention point. Promoting parenting behaviors that improve child cognitive development may be a more effective and direct strategy for practitioners to adopt, especially for disadvantaged children.
