The Earlyears Soft Baby Blocks includes four separate blocks that feature a different animal, picture, shape, pattern, or texture on each side. Each block makes a different sound including rattle, jingle, and crinkle sounds making each one enticing for baby. Each block is made of safe and soft fabric. The insides are a sponge material so they’re soft and easy for your child to grasp. That also means no hard sides or sharp edges like other blocks.

Your baby can learn early on the recognition of colors and animals just by playing with blocks. Soft fabric filled with sponge material. Each feature different pictures, shapes, patterns, and sounds.
