Ok, guys, the OP said a temp in the range of 37-39. So, 37 isn't a fever (I don't dose mine unless it gets to at least 37.5, unless he repeatedly claims a raging headache) but 38-39 most certainly is.
The NHS website recommends children stay at home if their temp is over 37.5.
Here's what the NHS has to say about sending ill children to school www.nhs.uk/Livewell/Yourchildatschool/Pages/Illness.aspx and here's what it has to say about fevers www.nhs.uk/conditions/feverchildren/Pages/Introduction.aspx.
No teacher would thank you for sending your child in only to vomit at school (nor would that be fair on the child), yet schools do now make you feel threatened if you judge that your child is too unwell to attend.
This past 6 months DS (5) has complained of recurrent headaches and stomachaches. I couldn't and wouldn't keep him off school every time he says he feels unwell. He went in on Calpol for 2 weeks with his headaches in Oct, and for most of the past term with stomachaches. BUT if his headache/stomachache is ALSO accompanied by a temp of above 37.5, then I know I have some objective indication that something worse than usual is up. I'm not some idiot who measures his temp every morning just for fun, and then keeps him off if it's slightly high, and I doubt the OP is either. However, if he says he feels ill, I use measuring his temp as an objective way of deciding whether or not he has to go to school anyway. If he feels ill AND ALSO has a raised temperature, it's usually a sign he's about to get worse.
He had Norovirus, infected eczema, and bereavement leave last term, so I got the nasty red letter on low attendance from school. My first thought (after I got over feeling offended and upset) was "surely he hasn't been ill an unusual number of times; half the country got Norovirus FGS". Then in Jan he got a bad cough, tummyache, temp above 38, and bone pains for over a week, and I got worried that maybe the school was right and he had actually had an unusual number of illnesses, and might actually have an underlying medical problem. I called his GP to discuss this, and the GP clearly thought I was overreacting. He said that there was nothing at all unusual in the number and range of illnesses my child had had -- for his age. (And yes, DS has had various checkups for his various symptoms, but the GP doesn't think that they add up to a "pattern" of illness - just bad luck in having had several separate things in a row.)
So the OFSTED cutoff for deeming the number of absences suspicious bears absolutely no resemblance to what the NHS deems within the range of complete normality for a child of that age. This disparity does not make sense.
All this guff about this sort of thing adding up to missing an entire year of school etc is daft when you're just talking about a reception-aged child. I'm certainly counting on DS having fewer of these illnesses over time. If he's still being ill at this rate next year and the year after, then I'll be the first to worry about it, thank you very much OFSTED, and not just because of the missed school.
Last Thursday night, just when I thought we'd almost made it through a clear half term, he had D&V, so another 1 day off school. I'm fully expecting a call from the EWO one day, and plan to invite them to come over at 3am and help me clean up the vom next time if they don't believe me.
