The Developmental Cup Set is a training set that teaches babies, toddlers and preschoolers to drink from an open cup and safely use a straw. The developmental drinking system starts with the 2 oz Tiny Cup (4 months +), followed by the 4oz Mini Cup + Straw (9 months +) and concludes with the 8oz Happy Cup + Straw (2 years +). Each tool supports important milestones such as lip closure, lip rounding and tongue elevation. These drinking milestones promote a safe swallow and healthy oral and speech development. 6 months +Benefits•Provides the tools needed for the 3-Phase Developmental Drinking Method (Dawn Winkelmann, M.
