11 week old baby using a pillow

So first I would like to say that I’m not here to be bullied or told how I’m doing everything wrong. I’m here looking for moms who had have the same problem as me, and yes I recognize that it is a problem… my sweet baby boy Liam won’t sleep without a pillow. Me and my wife had tried everything…like… EVERYTHING! and he still won’t sleep more than 30 minutes (if he doesn’t wake up as soon as we put him down) unless there’s a pillow to prop him up. He has really bad acid reflex and I’m not sure if the pillow helps with the pain and that’s why he loves it so much or what, but idk what else to do.

Any other mom here going through the same thing?
