Persistent vomiting and diarrhea can be dangerous in kittens, so you have good reason to worry. The biggest concern is that he can quickly get dehydrated, which is life-threatening. In order to keep this from happening, he will need to see a vet, so they can administer fluids. They also may be able to find the cause of the Diarrhea/vomiting and correct that. With kittens, I am mostly concerned about infections. Luckily, most of these are treatable, so getting him to the vet as soon as possible will make a big difference in keeping him from getting dangerously sick. I hope that helps and Theo gets well soon.
