Developmental Cup Set
I love that the cup, lid and cap are all silicone. These cups are not spill proof. I wish the straw had an extra piece to keep it inside the lid. My little guy likes to pull the straw out which makes a mess. The sizes are perfect as my little guy grows. Overall I love the EZPZ line of plates, bowls, spoons and tooth brush.

RECOMMEND!
Great tool to introduce liquids via open cup to my 6mo old. The weighted bottom and shape is a wonderful design.

Absolutely THEE best for kids of all ages!
We tried other straw cups for our 10 mo old, these truly are the smartest design! The "weighted" bottom so they aren't easy to knock over, the fully closed lid with only an opening for the straw so no leaking when not yet using them without the lid/straw, the "guide bumps" on the straw for the baby/toddler to feel and automatically purse their lips around, and the size options for growth are ALL so smart and help the transition to go well. We LOVE these in every way!
