My 21 year old son had the same problem until he was 18. Michael landon(Bonanza) had the same problem until he was in his late teens.... I suggest you just help him and monitor the problem... it can be just the fact that he sleeps too soundly...very common! I think it's more of the parents' problem (as was the case of ours); too much stress. TRUST ME...HE WILL OUTGROW IT!
