my advice is to let him outgrow it naturally. especially if the only time he does it now is when he is stressed or tired. i think he has shown a lot of maturity and is being a really good boy not doing it all the time just out of habit - a lot of adults have bad habits they don't have the fortitude to break. so good for him. if he needs comfort during stressful situations i don't see why you would want to take that away from him. i really disagree with parents who stress their kids out trying to pressure them to quit doing something that is natural, harmless, and provides comfort to their child. the more you pressure him, the more stressed out he will get, and the more he will want to suck on them, but he will know that to make you happy he can't, which will cause him guilt if he does it, and more stress if he doesn't...agony! why put them through that! most kids stop naturally when peer pressure kicks in and they don't want to do it around their little friends, anyway. i just don't think it's worth putting even more pressure on him.
