Rising numbers of pre-school children are being allowed to play with tablet computers and watch TV in bed, research shows.
Almost one in ten youngsters aged up to four are glued to programmes under the duvet, despite parents being warned of the health hazards of night-time viewing.
Rising numbers of toddlers are also using their parents' smartphones to access apps, while many already have their own tablet.
Experts claim these so-called 'iTods' and their parents increasingly see constant access to screens as a normal part of life.
Research body Childwise surveyed 1,034 parents of pre-schoolers aged between six months and four years for the study.
