I would definitely suggest leaving food available to him at all times. (free feeding) Especially if he's having appetite issues. If he's not eating enough, his blood sugars go low and that causes them to not want to eat. So it puts you into a cycle. He's very young and I wouldn't dream of trying to feed meals at this age.

Also, he's teething. His mouth may be sore which could be causing issues as well. Check his teeth to make sure he doesn't have something going on there.
