She told The Telegraph: “To have sweets on your birthday is one thing, but having them on every other child’s birthday is another.”We had sweets in school before and the children were getting greedy and unpleasant about it, grabbing them and that sort of thing.”There was no aspect about it that was pleasant.”She added: “It’s really important that parents understand that we’ve got the children’s well-being at heart. It’s not because I don’t like sweets.”There’s this assumption that every celebration has to involve sugar and I think we need to change children’s perceptions about that as well as parents’ perceptions.”Almost 9 out of 10 hospital tooth extractions among children aged five and under are due to preventable tooth decay, figures from Public Health England show.The report, published last week, found that youngsters are eating the equivalent of about eight sugar cubes more than the recommended daily limit.It also revealed that pupils missed at least 60,000 school days in the last year so they could have rotten teeth extracted in hospital. A primary school has banned sugary treats after the headteacher said parents who want their children to eat healthily are being “shamed” into buying unhealthy snacks.Chasey Crawford-Usher, the headmistress of Wateringbury Primary School near Maidstone, Kent, said there is an expectation that every celebration has to involve sugar and parents are being pressured to go along with providing foods which fuel obesity and tooth decay.Ms Crawford-Usher has been criticised for the ban, which comes four years after she prohibited fruit juices because she said they rot children’s teeth.Olympic race walker Tom Bosworth, 29, was among those who waded into the debate, tweeting: “This head teacher is a moron. Common sense needs to be used here.”What is happening to society to ban kids from having sweets on their birthday. Ban them every other day if you like, but let a child be a child on their birthday though.”Another social media user wrote: “A prime candidate for being a senior member of the fun police.”But others agreed with the head’s decision and said she had set an excellent example to other schools.Ms Crawford-Usher insisted that the well-being of pupils should be the priority and she was not the fun police.
