Lovevery® combines the best of neuroscience and Montessori philosophy to create stage-based toys that support your child's brain development. The Friends of All Shapes Puzzle will engage your child—and build important milestone skills—starting at 13 months. Around this time, your toddler is interested in learning that similar objects come in different sizes and fit nicely into each other. Your child may learn to nest the set of felt baskets on their own around 24 months. Be amazed by all your child can accomplish—and have fun learning together through play. Includes a free Digital Play Guide and access to expert content with purchase.
