My son has bad nightmares; last night, there were zombies in his dream. He said he got the idea from Scooby Doo - so one thing we can do is to cut back on any TV shows that have scary monsters (even cartoon ones, like Scooby Doo).

Is there anything else we can do to help him reduce (or manage) his nightmares? I feel so helpless... and he has been learning to dread falling asleep. The only thing I could do is to tell him to come snuggle me or his mom - or if we're not around, to snuggle the family dog. Any other ideas?
