The Battat sort & stack nesting cups provide hours of fun and many developmental assets for your baby or toddler. Not only will they love stacking them up and knocking them back down (this is the best part!), they’ll love to learn about the different animals, colors, and numbers on each bucket. Square, circle, Star or triangle… they’ll learn to match the different shapes on the lid and watch the pieces fall into the bucket. This classic toy of nesting cups helps with your child’s hand-eye coordination and fine motor skills, as they try to stack all the cups up and up. Introduces the concept of basic physical, accuracy, color and shape sorting and counting. In the first years stacking up cups is just a classic, as we all did it. Without the stickers, this set becomes a water and sand toy as well. Sandcastle? we got it cover! one of the best baby toy cup toys there is!
