Poor mama! You sound tired, too! I totally agree that him screaming for an hour isn't restful for either of you.
I don't know what other people do, but our "winding down" routine starts when they come inside from outdoor play around 12:40. We tiptoe into the house, and older kids go potty while littler kids get new diapers. I close all the curtains in the house and turn out the lights, and I start moving really slowly and stop making eye contact (that's important). We only whisper from that time forward. When the kids are done going potty they have a small snack, then they sit on the couch and look at a book of their choice (quietly, to themselves). Then we tiptoe downstairs and quietly brush our teeth together in the bathroom with the light off, and then I have a soft, slow song that I sing while we go into the nap room (where I have really dark curtains, so it's quite dark), and I tuck the kids in and give them kisses. They are usually asleep by 1:05. I usually stay in the room until they're asleep, sitting in a rocking chair and humming, but if your kids aren't used to that, it may be distracting. I used to have a nap space set up for myself, and would just lie down and take a nap with the kids. Don't know why I stopped doing that, actually!
