Although evidence is mostly anecdotal, it has been suggested that there may be a link between inappropriate infant feeding and later speech development. Selley et al (1990) identified seven common factors in co-ordinated neonatal feeding and speech production, namely: rhythm, breath-control, lip tone, delicate tongue movements, speed of muscle movements, well developed sensory feedback and a relaxed feeding situation. Breastfeeding and open cup feeding fulfil these criteria by encouraging development and maturation of these factors, while promoting a positive feeding experience.

Some speech therapists still believe that the action of drinking from a lidded cup can interfere with the more complex swallow required when using an open cup. The latter action helps to build the muscles required for proper speech to develop.

Sara Rosenfeld-Johnson, a speech pathologist from Tucson, Arizona, presents seminars around the USA and is one of the most outspoken critics of the ‘sippy cup’. She does however concede that those speech anomalies are easily treated by switching back to regular open drinking cups (Eig 2002).
