Toddlers now become much more curious and adventurous and love to sort, hide and stack things. They recognise colour and love familiar sounds; high tones are most readily heard. A process of learning and doing develops, and babies learn to name things, to sort things and put things away. They will follow your example and it will not be long before they can do it by themselves! This strong lockable box comes with two sets of three-dimensional sorting blocks for hours of shape and colour matching activity.
