Toddler throwing up

Looking for advice!

My 18 month old, like the rest of the house, has had a lingering cough for a few days after a virus. He was laying with me on the couch and as he was falling asleep started to cough a bit and then he threw up all over me and the couch. I figured it happened because he was coughing and cleaned him all up plus I had to change my clothes because I was covered as well as the couch. He laid back down with me to fall back asleep and 2 hours later he threw up all over me and the couch again. I’m at a loss on what to do because clearly he is sick and it wasn’t just a cough but what do you do with a child that’s too young to tell you he has to throw up? I can’t just have him throwing up all over me every couple hours. But I also don’t want to put him in his crib and have him throwing up all over himself. Anyone have any tips?
