The OXO Tot training cup will help take baby from the OXO Tot Sippy cup to a regular cup, while building their confidence. The translucent lid insert has perforations all around the edge to control the flow of liquid when your child tilts it. The Training cup is also designed to spill gradually, so if it is knocked over there won’t be too much mess, but children will still learn not to knock the cup over. When your child is ready, simply remove the perforated lid insert and the cup becomes a normal cup. The cup is BPA, PVC and Phthalate free.
