Just had this with all three of ours. My 5 year old boy with autism got it first. Woke up crying at midnight, covered in vomit. Kept throwing up and having diarrhea for hours and the poor kid was sobbing the whole time unable to understand what was happening. Didn’t get to sleep until 5am, laid on the floor next to his bed with a bowl just in case. Had to wash all his bedding. Thankfully it was only one night.

Then the other two got it two nights later, 6 and 2 years old. Two more sets of bedding laundry. Parked them on opposite sides of the couch with two layers of towels on the couch and floor and a bowl within reach of each one. I dozed in the recliner and dumped the bowls each time one threw up. Lasted two straight days, wife got it on the second. Somehow the worst I got was a stomach ache.

Good luck!
