I echo everything that Katherine said. I wish I took more advantage of how portable they are in the '4th trimester.' It's awesome your DS is a great traveler, but I also respect that that can present some inconveniences for the parents.
My DS, spirited/textbook, also refused the paci/soother and just chewed on it. Have you tried different kinds? They have softer ones that resemble nipples better. Mine never took to one, but it might be worth a try. DS eventually took to a lovely when he was age appropriate that he chews, strokes, cuddles and I bought 5 of them to ensure we have one around! =)
DS was also not having any Sh/pat. Interesting, huh? Firm, heavy/gently hand and patting worked, too. Also, we used a sound machine and still do to this day. We switched from white noise to the ocean sound as I found that it was a bit less harsher on our ears. But for this age, loud, rhythmic, white noise is what they're used to!
Our DS also hated the swaddle, (hmm, they could be twins!), but he did well with the swaddle with both arms out. I think the slight pressure on around the torso and legs being able to be constrained somewhat helped him?
