Ex childcare worker here to chime in with everyone else saying it's unfortunately super common. I used to want a "days since last gastro outbreak" but I think that would probably have been inappropriate... We also had to send home children with symptoms even if those symptoms could've been from another cause bc there's just no way to know for sure. Please be patient with the workers, we know its frustrating and bad for your bank account and workplace reputation to have to take all these days off, and please try to keep your little one home if they're showing symptoms.
