title: Caregiver self-report of children's use of the sippy cup among children 1 to 4 years of age.
abstract: OBJECTIVE
  This research examined the prevalence of the use of the sippy cup, as compared to the baby bottle, among children 1 to 4 years of age.
  
  
  METHODS
  Using a population-based telephone surveillance survey in Ontario, caregivers of children 1 to 4 years of age were asked about their child's use of the sippy cup/baby bottle from the Rapid Risk Factor Surveillance System Module: Early Childhood Tooth Decay.
  
  
  RESULTS
  Most caregivers reported that children 1 to 4 years of age were currently using the sippy cup (69.7%), with the proportion increasing to 94.4% when including children with past use of the sippy cup. Younger children were significantly more likely to use the sippy cup, and 10.8% of children 4 years of age continued to use the baby bottle. Diluted fruit juice was the most frequently used liquid in the sippy cup (58.2%). Most of the caregivers did not report the use of the sippy cup at night.
  
  
  CONCLUSIONS
  Caregivers need education as to potential increases in exposure to sugared/acidic liquids through the use of the sippy cup. Future research is needed to understand the extensive and prolonged use of the sippy cup/baby bottle by young children.
