From the Guidelines

Bottle feeding past 1 year old does not have a direct impact on speech development, but it is crucial to transition to cups around 12-18 months to support proper oral motor development and reduce the risk of indirect effects on speech production. The primary concern with prolonged bottle use is its potential to affect oral motor development and dental alignment, which may indirectly influence speech production [@\2@]. Bottles with nipples require different mouth movements than those needed for speech, and overreliance on them may delay the development of more mature oral motor patterns necessary for clear articulation.

Some key factors to consider when assessing the impact of bottle feeding on speech development include:

  • Oral motor development: Prolonged bottle use can affect the development of oral motor skills, which are essential for speech production [@\2@].
  • Dental alignment: Extended bottle use, especially during sleep or throughout the day, can potentially affect dental alignment, which might indirectly influence speech production.
  • Risk of ear infections: Excessive bottle use can increase the risk of ear infections due to milk pooling in the oral cavity, and recurrent ear infections may affect hearing and subsequently speech development.

To minimize potential indirect effects on speech development, parents should:

  • Gradually introduce sippy cups or regular cups around the first birthday
  • Offer cups during meals while slowly reducing bottle feedings
  • Encourage varied mouth movements to facilitate speech development
  • Monitor oral motor development and dental alignment, and consult a healthcare professional if concerns arise [@\2@].

From the Research

Bottle Feeding and Speech Development

  • There is no direct evidence to suggest that bottle feeding past 1 year old interrupts speech development 1, 2.
  • However, prolonged bottle use has been associated with various health issues, including dental caries, iron-deficiency anemia, and child overweight or obesity 1.
  • Some studies suggest that children with speech sound disorders (SSD) are more likely to have orofacial dysfunction and malocclusion 3, 4.
  • Orofacial function and malocclusion can be related to speech development, but the exact relationship between bottle feeding and speech development is not well-established 3, 4.
  • Speech and language development should be consistent with a child's overall development, and early identification and intervention can assist in educational planning and improve long-term outcomes 5.

Factors Associated with Bottle Feeding and Speech Development

  • Hispanic ethnicity, multiparity, low income, low education, higher caregiver weight, and not initiating breastfeeding have been associated with bottle cessation at older ages 1.
  • Married parents are at risk of late weaning, and parents who allow their children to sleep with milk bottles in their mouths in bed at night may be more likely to have children with delayed weaning 2.
  • Children with SSD are more likely to have co-existing neurodevelopmental disorders, and orofacial dysfunction may be linked to an increased risk of malocclusion 3, 4.
