A., I can't speak to the tummy aches and tiredness, but I want to share what I've learned about those vocal ticks. My son has been producing vocal ticks off and on since he was 3y.o. (now 9). Vocal ticks are more common in boys, and they usually out-grow them by the time they hit puberty. Since he can't control it, "nagging" won't help -- and may even exacerbate -- the problem. But helping him become aware of situations or times of the day when he does it more can be beneficial. If you google "vocal ticks," you'll find some reliable, helpful websites.
