I wish I had better advice, I haven't really experienced the same, but that sounds like a lot going around at once (mixed in with bad allergy season etc) and I could see why it may be taking longer to fight off .... the diarrhea for your DS may be related to antibiotics
YES. My DS has been sick continuously and DD and I have had it off and on. I keep thinking he's finally getting better and then the cough and runny nose starts up again. He's been tested for allergies and tested negative, but I swear it has something to do with the pollen/etc. irritating his airways anyway.
Try getting seen by an ENT and have tonsils and adnoids looked at? That's the only thing I can think of you haven't done. That and maybe hire a cleaning company to come in and give your house a good deep clean just to be extra thorough...
You can get an at home mold test kit at home depot. That could be another possibility?
I'm so sorry, we all have rough months of illness, but yours does sound extreme. All I can think is sanitize and start thinking outside the box on health care (ie.... something chronic not just multiple viruses or allergies)
My dd will vomit and have diarrhea as a result of congestion from allergies. It's all drainage related. I'm sorry, that sucks. We are right there with you!
Re: Okay this might sound a little crazy- PR
Just everyone getting the bug one after the other and then something new popping in and starting the cycle over.
DS had a massive sinus infection, cough, eye infection, vomiting the other day and now diarreha (sp?).
DD has had a cough, eye infection ,ear infection, sore on the outside of her lip and fevers.
@NotSharknado DD has allergies but this is way different then last year.
But I agree with PP that said she opens the windows and disinfects everything.
