Insights
Late bottle-feeding was common in a well-educated cohort, linked to maternal return-to-work timing. Further study is needed on prolonged bottle use
Area of Science:
- Pediatric Nutrition
- Infant Feeding Practices
- Maternal Health
Background:
- Understanding the transition from breastfeeding and bottle-feeding to solid foods is crucial for infant development.
- Factors influencing the duration of these feeding methods require further investigation.
Purpose of the Study:
- To investigate the transition from breast and bottle feeding to solid feeding.
- To identify factors affecting the duration of breast and bottle feeding in infants.
Main Methods:
- A cohort of 191 healthy, full-term infants from a community sample was followed from birth.
- Feeding practices were assessed until complete weaning from breast and bottle feeding.
- Participants were from middle-class families with relatively well-educated parents.
Main Results:
- Over 90% of infants were breastfed for at least two weeks.
- Later maternal return to work was associated with earlier breast weaning and later bottle weaning.
- A significant proportion of infants continued bottle feeding beyond 24 months (40%), 36 months (16%), and 48 months (8%).
Conclusions:
- The high rate of prolonged bottle-feeding in this cohort was unexpected and correlated with maternal work status.
- The long-term effects of extended bottle use on infant growth and adiposity warrant additional research.
Objective:
To understand the transition from breast-and bottle-feeding to solid-feeding and factors that might affect the duration of breast- and bottle-feeding.
Design:
Cohort followed up from birth with relatively well-educated, middle-class parents.
Setting:
Community sample recruited from 3 suburban newborn nurseries (a teaching hospital, community hospital, and large health maintenance organization).
Participants:
One hundred ninety-one healthy full-term infants.
Measures:
Assessment of feeding practices through the ages of complete weaning from breast- and bottle-feeding.
Results:
More than 90% of participants breast-fed for at least 2 weeks. Infants of older mothers were weaned from the breast later than infants of younger mothers. First-born infants were weaned from the breast earlier than later-born infants. Eighty-four percent of infants bottle-fed at some time during the first year of life. More than 40% of the cohort was still receiving bottles at 24 months of age, 16% at 36 months, and 8% at 48 months. The duration of breast- and bottle-feeding was related to maternal work status; mothers who returned to work during the first 3 months postpartum weaned sooner from the breast and later from the bottle than women who returned to work after 3 months postpartum.
Conclusions:
The frequency of late bottle-weaning in this well-educated, middle-class cohort was unexpected and was related to the timing of the mother's return to work. The impact of prolonged bottle-feeding on later growth and adiposity deserves further investigation.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
