These cups won't strain your heart, because they're simply made with too much love! Each set of 5 comes with multicolour edges, and each edge has a unique pattern to stimulate baby's motor skills upon touching. What's more is that all of Hearts™ edges are made with a soft-touch material that has no paint, and is safe for baby to put in his or her mouth to help prevent unwanted injuries. These cups are multipurpose - as they can stack, scoop, strain, spill, pour and rinse - meaning they will occupy baby for hours on end in the tub. Also, numbers help your child learn to count, while large-to-small nesting helps build hand-eye coordination and teach sizes.
