Extract from Sunday Telegraph article:
"Baby seats, booster chairs and wooden floors rob infants of the chance to crawl, leading to learning problems, child development experts have warned.
Babies are spending less time on their stomachs, which is hampering their ability to crawl. The early movement is vital to balance, hand/eye co-ordination and motor skills, which all play a part in children's ability to read and write, says Sally Goddard Blythe, director of the Institute for Neuro-Physiological Psychology, in Chester.
She argues, in a book due out next year, that babies' first playground should be the floor. "Children are spending more time in car seats, sitting in moulded baby chairs, using baby strollers," Mrs Goddard Blythe told The Sunday Telegraph. "The sleeping on the back campaign, while absolutely necessary, means there is less of a tendency to put babies on their stomachs when they are awake."
