I sleep really poorly if there isn't another adult with me (namely DH). Guess I have terrible sleep associations 😏
My kids have never really had tangible things to help them sleep, but they have been rocked, patted, boobed, and co-slept. Both sleep through and only wake to go to the toilet. They're 3 & 5.
ETA: I also sleep way better with the fan on and used to only be able to sleep with white noise. It's not just babies who have sleep associations!
