We designed the NumNum Straw Training Cup and chose a valveless straw with pediatric specialists who understand the challenges and development stages of infants and toddlers to meet their unique needs and motor skills development.

Our short, narrow, and valveless straw was designed to promote oral motor skills (e.g. proper tongue tip placement, and lip closure that plays important roles in speech development and palate formation) and allow for a more natural and consistent flow of liquid to make it easy for your little one.
