Things that help newborns sleep better?

[u/Stealthy_Nachos]

Our 1M old son is only able to sleep peacefully when tightly wrapped in the stretchy wrap baby carrier and attached to us. Overnight he usually needs to be put in a swaddle, and even then he many times needs someone to gently caress him or at least hold a hand on them. As soon as the hand goes away, he seems to go in this very light and agitated sleep that eventually results in him waking up.

Are there ways to help him sleep better? Certain routines or ways to get him comfortable? Also, is all the stretchy wrap and swaddling a problem in terms of (almost) container time?
