Swaddling really does help,also something warm and soft as extra gentle pressure on babies tummies your hand or for when you just can’t hold anymore a folded soft blanket, a warmed heating pad(turn it on for low till warm then OFF before putting near baby.
When all else fails place the baby in a safe place with white noise (static from radio or the like) then remove yourself from the room for 10 minutes put on some music you enjoy to counter the crying (headphones) so you can try to regain your patience then start all over again. most do outgrow this by three months hang in.
