He isn't able to chew them? Or do you mean he can't really swallow them without his tongue? Does he voluntarily drink the bug juice (or are you feeding him the whole crickets and just helping him out?) Sorry, I haven't read through the whole thread/all of the threads you posted so I don't remember/know how you are dealing with food.
Are you weighing him? I would weigh him and decide what to feed him based on his weight. If he isn't growing the way he should be/is getting skinny, then feed him more. If he is gaining too much weight AND looking fat, then feed him less. If he is gaining a lot of weight, but is also growing and not looking fat around the hips/cheeks/casque then I wouldn't decrease the feeding. I think that would be the best way to go about it. Skipping days is fine as long as he is getting enough food on the days that he is being fed.
