Everyone's words are so helpful for me. I've not had the conversation with W about what to do if he's having nightmares, but I will. I haven't seen/heard him during a nightmare (I sleep deeply), but when I'm falling asleep and he's drifted off just before me, he is jumping about every 3 to 5 seconds. Some of the jumps are little, some big- the big ones wake him, and he hugs me and says sorry. I've asked him if he's having nightmares with the jumps and he says no, but perhaps he's just not ready to share.
