Hi Kimmy,
Not really sure what to do here, given the age. One word of caution though. You may see feeding of raw garlic recommended some places, as this is a common remedy for dogs -- but in cats, this can cause a serious, or even deadly, form of anemia. As well, there is a symbiotic relationship between fleas and tapeworms, fleas being the intermediary hosts. At the very least, you could try lightly bathing the kitten periodically, in order to lessen the risk of them swallowing any of the fleas. Good luck. Hope you are able to find a better solution soon.
