Here's a fun new twist on stacking cups and nesting dolls, colorful oversize chicken eggs! Nest them to play hide and seek. Stack them up then let them fall. Little chick becomes a bigger chick, and bigger chick, and bigger chick! These stackable eggs teach children about size relationships and matching pieces. They can develop their fine motor skills and spatial reasoning just by building up a tower of eggs. And while they’re learning, they’re also having tons of fun. Each egg features a different chicken, designed to be fun an adorable with colors that are enticing to children. Plus, they’re all made from high quality plastic, free from both BPA and phthalate so they’re safe for your child. For ages 6 months and up.
