Kids constantly coming down with sick bugs

One of my dses went through a phase of being ill (running a temperature and being lethargic), recovering, and then going through the same thing, @Nightsatthelitten - it seemed like a never-ending cycle of illness.

In the end, I wondered if he wasn’t recovering properly, and that made him more prone to picking up the next infection, so I started giving him a vitamin and mineral supplement, and a tonic for children - I hoped that, if I built him up, he might be better able to fight off the next bug, and it seemed to do the trick.

Do they have packed lunches? Is the school kitchen clean?!

I think it sounds often for that age. When the kids were under 2 they were sick almost monthly in the winter months with cold type symptoms ( they were in nursery) but past 3 they’re rarely sick. We have not had sickness bugs very often at all.
I agree with a pp that probiotics helps and we are very on it with washing their hands very frequently too, as well as reminding them not to put their hands in their mouths..

Year 2 and 1 in childminders.

Oldest child has had maybe 3 sick bugs in her life. We've not had one for a year (that bug took out two thirds of her class!). We get lots of colds over winter but nothing serious enough to keep off school, just sniffles.

Littlest has not had a sick bug yet (plenty of colds though).

Mine are Year 2 and nursery age. We have maybe one sickness bug a year (in fact we've all just got over one), but aside from that they are rarely ill enough to miss school/nursery. Every other month does seem a little excessive.

My eldest hardly ever.
My youngest, more frequently - plus she seems to throw up more easily in general even without an actual sickness bug (car sickness, she vomits with a cold, anytime she has a fever, she vomited with chickenpox, with an ear infection)

My younger daughter is a great believer in gut health and has given her two children, ten and seven, probiotics since babyhood. They have never missed a day of school. My older daughter dismissed this as twaddle but when her two similarly aged kids kept coming down with all sorts of illnesses, from nursery on, she started giving hers probiotics ( initially secretly and then a bit defensively) and they've never looked back. I have no axe to grind either way, just offering anecdotal evidence. I myself had never heard of probiotics when mine were little and getting everything under the sun - they seemed to specialise in strep throat and ear infections. Based on what I've now observed, I would definitely have given it a go.

Mine are primary and secondary now. I’d say not that often. I mean they might have a sniffle here and there, but rarely something that would keep them off school. I think youngest has missed 1 day this year and older one maybe 4 days (half of those because the school sent her home, they are very quick to call you to collect them 🙄 but also very quick to question you if you ever call them out in the morning). I’d say this is similar year on year, we only miss a couple days.

Did yours go to nursery? That seems to be the biggest difference. Mine got all the illnesses out of the way between 9 months and 3. But friends who didn’t go to nursery are off sick a lot. I think they all have to go through it, but some of it go through it younger.

How old are they? Mine got sick quite a bit in reception but the eldest is in y6 now and hasn’t missed any school this academic year so far
