6 months and up. These Soft Stack Baby Bricks are the perfect way to introduce infants to blocks. Infants can interact with these bricks in all kinds of ways because their soft outer material and firm, plastic construction make them both pleasant to hold and able to withstand the rigors of infantile sensory exploration. The bricks also connect to one another very easily, so infants may even build something while they play! Includes a zip bag for easy cleanup and storage. Set includes 32 blocks.
