Hi. It sounds like Milo is pretty sick. If he is sleeping a lot, not eating, and vomiting, he needs to be seen in order to find out what is going on. Since he is young and only 6 months old, if he is not fully vaccinated Parvo is definitely a possibility. He could have also eaten something that he shouldn't have. Parasites are also a possibility at this age as well. He is most likely sleeping a lot because he is lethargic and not feeling well. I would recommend getting him seen right away so that you can get on top of whatever is causing this and get him some supportive care no matter what the cause is. Good luck and I hope he feels better soon
