Black and White Animal Tails book
Research has shown that the secret to infant visual stimulation lies in high-contrast colours. The development of a newborn's eyes - the structures of the retina that perceive colour, haven't matured enough to perceive the values and intensities of red, blue, pink, yellow, purple and green. Black and white are the easiest for babies to perceive and interest in these starkly contrasting colours will pave the way for your baby's brain development.
The tails provide added material for the tactile development of the baby.
