My three preschool DC and I have a tummy bug but my 9 yo is so far fine. I was up pretty much all night last night and typically we all settled at around 6 am, then my alarm went off at 7. I got up and woke 9 yo, made her lunch, had a shower etc then woke the others and got them dressed before driving 9 yo to school. We were five mins late because of having to pull over because of two of her siblings being sick. I saw my friend on the way back to the car and she noticed the kids looked poorly so I explained that they were and she said she'd have kept 9 yo home too and stayed in bed and that if one of her dc is ill and off school she keeps the other one off too.
I know 9 yo will probably catch it but surely she'd end up missing loads of school if I kept her off every time her siblings are poorly? Or am I in the wrong and spreading illness unnecessarily?
