Roll & play, push & learn this colourful ball is so much fun! Hamleys knows the kind of toys that babies love & how to make them interesting & engaging. This Black & White Jingle Ball is a sweet little toy & a development tool also. Babies will be delighted to roll it around & hear the funny jingly sound. With all the different textures to explore, this Jingle Ball will never be out of your childs hands. Babies are introduced to the world through their senses; touch, sight & sound. To help little ones learn about life around them, Hamleys have introduced an exciting new Baby range, the Black & White collection. Designed by experts in child development, this Black & White Jingle Ball stimulates your baby using texture, sound & contrasting patterns. Babies can only see in black & white in their early months & more colours are introduced as their visual development improves. The high contrast colours in these toys grabs a babys attention & encourages learning. The black & white colours stimulate childrens vision & depth perception & have been proven to generate physical activity in very young infants, such as wiggling, kicking & arm waving. Dr Dagmara Annaz, child development expert at University College London, who helped design the range, said: Hamleys leads the way when it comes to designing innovative & stimulating toys. We wanted to use our expertise & knowledge to create an age appropriate & engaging range for very young children which would actually help their development, in addition, of course, to being fun toys to play with.
