Inappropriate baby bottle use is associated with tooth decay, anemia, and overweight, and it may adversely affect dietary patterns. Parents often do not follow guidance to wean by 18 months of life. We piloted a brief, counseling-based weaning intervention in an urban WIC agency among primarily Hispanic parent/toddler dyads. At baseline (n = 48), toddlers consumed a mean 4.7 bottles/day. At follow-up (n = 39), the intervention group consumed fewer mean bottles/day than controls (0.09 vs 2.0 bottles/day, P < .045). Half the toddlers in the experimental group and one third of the control groups weaned completely. Parents of weaned children were satisfied with the outcome.
