BraveJusticeKidsCo. presents: 2 Pack Itty Bitty Silicone Developmental Drinking Cups. These cups are designed for babies who are transitioning from sippy cups to regular cups. Learning how to drink out of a regular cup can be a big challenge for a toddler. That's why we have made this 2 pack available for parents, to aide in this development and transition to regular cups. As a parent you can help take your child to the next level by facilitating muscle memory and motor functions with these transitional silicone drinking cups. This 2 pack has one developmental Itty Bitty cup with handles, and one without handles. The cups are weighted on the bottom along with non-slip grip to help keep the cup from spilling.
