you may also tell your son not to panic if nothing happens for a few days, it's not unusual for the eyes to clear up after a couple of days and the actual shed not to take place for up to a week after that. some snakes resume normal activities during this "clear" period and may even eat, others just stay hidden and want nothing to do with food until after it's all over. either way, it's nothing to worry about, for most snakes the shedding process does not seem to be overly traumatic. hope this helps a bit
