Mind Shapes are a FANTASTIC choice for infants. When babies are born, their eyesight is not yet fully developed. The bold and contrasting images on these soft blocks are designed so that baby can actually SEE them. Plus they crinkle and rattle! And judging from what we've observed, they must taste great, because babies love to chew on them too. This is a great brain-building toy! Recommended for ages 0 to 2.
