'Many primary school pupils lack basic motor skills'
Many five-year-olds cannot hold a pencil, sit still, dress themselves or use a knife and fork when they get to school.
Sally Goddard Blythe, a child development expert, explained her research findings on BBC Radio 5 live: "My feeling... is that there should be a greater emphasis on the developmental testing of children's physical skills at key stages in development.
"These little baby reflexes are tested at birth by a paediatrician," Goddard Blythe told Victoria Derbyshire.
"Unless a problem is found at that stage, they are not tested again. Teachers are not trained in how to detect and how to remedy underlying problems."
