I didn’t say that, gilly.
I said if rickets is on the rise, surely that underlines the importance of medical examinations in school, and parents being notified of findings
Meaning that if children’s health was generally so poor that rickets was increasing, then it was all the more important that they should be monitored (weight and height) to flag up early signs.
I never said schools should test for vitamin D deficiency.
In answer to a question from you, I said that if a child had rickets, as opposed to a mild deficiency, there would be physical signs that could be picked up.
In answer to your dental question, no I never saw that, but early eruption of teeth is well documented and occasionally babies are born with one or two teeth which obviously makes it a bit uncomfortable if the mother wants to breastfeed ?
