You can't go get her now disrupting the class, her being settled, in case she poos herself. That said I'm also thinking perhaps you should go get her because if she dosen't make it to the loo it could be embarressing for her.
The teacher should not have let her anywhere near the class if she has had a dodgy belly. Most schools have a strict 48 hour policy after sicness and/or dirrohea. I know if I told my Ds teacher shed be frogmarching myself and Ds out of the school gates.
She's there now and the teacher is right, if you had taken her home your dd would have thought the way to get brought home is to scream, making the whole thing worse (I know, DS2 cried EVERY day for a year and half when I left!). BUT, you really shouldn't send a child to school within 24 hours of being sick or having diarrhoea - it't not fair on her (imagine how she would feel if she didn't make the loo on time in school) or the other kids.
We all make the wrong decisions sometimes though, there's no point beating yourself up about it.
Reality, these situations are always a hard call especially if your child seems well. I agree she should not have gone in since it is so recently she had diarrhoea. I'd have said today off at least to be on the safe side - it's a bit unpredictable.
She probably only had it because someone else sent their kid in ill in the first place, so you're not alone
Don't beat yourself up. I think now the teacher has told you what to do you need to leave it in their hands. There's not much you can do now iyswim.
In those circumstances I think you were right to take her, I would have taken my boys. One episode of runny stools (hate that expression) doesn't mean that it is diarrhoea and if she is has been fine since I think it is a safe bet that she will be fine today.
Stop fretting, bet she is OK in class now, honestly.
AS a rule of thumb diarrhoea or sickness should be given a 48hour break at home. There could be other children in families where a bout of D&V could be very dangerous, small babies, people with type 2 diabetes, following chemo for example.
But you've done it now so just get on with your day. Put this down to an experience that you learn from.
One episode of the runs doesn't = tummy bug. I would have sent all of mine in if that had happened to them and they hadn't been again all night. I think you did the right thing. My DD1 cried every morning in reception. Luckily yr1 and now yr2 she is OK (She still says she hates school though!)
Well my ds has a cold and was very droopy at drop off. His teacher said he hadn't been too great the last few days, and he told me he'd asked to come home once or twice but they didn't bother to ring me
so I made it very clear I am available as soon as he feels poorly and they MUST ring me. It takes a lot for a kid like ds to admit he wants his mum.
I would ring/email the school office and tell them that you are worried and if she seems AT ALL PEAKY then you will be there in a flash and please can they not hesitate to call - leave your number so they have it ready if needed.
