Their deficiencies are so common that the government is to introduce a checklist of skills that children should possess by the time they start school.
Teachers are increasingly finding that on top of their normal teaching functions they're having to do things like changing nappies and helping children up the stairs - things parents should have taken care of long before start of school.
As I recall from my early schooldays, there weren't any children who lacked such basic skills. It would have been totally shocking if they had. My mother obviously had a very clear idea of what school readiness meant, and would have been mortified if I'd turned up at school in nappies.
It seems a lot of young children are simply not getting enough exercise and not using their muscles enough to strengthen them because they spend so much time looking at screens.
While nine out of ten parents considered their child ready for school, teachers said one in three children weren't. Some parental education is plainly much needed.
