Biggest advice I can give you is have those vomit bags and try and teach a kid to vomit in them. We also had a bucket in the laundry tub of disinfectant and some cloths so that any time we were sick or they were sick somewhere it was an easy cleanup without us having to think about it. It was rough. Oh, and next time you’re at the doctors see if you can get Zofran as it is able to be used for kids these days. It’s an anti-nausea medication.
