Try the Sounds for Silence CD! You can google it and listen to some of it! It is noises made by a peadiatrician that babies respond well too like wooshing and swhooshing noises! It also has some mozart music on there to use while you are feeding to help settle! Babies are used to loud noises from being in your belly so they respond well to this!
It worked well for me when my bubs wouldn't sleep at night!!! Put a cd player in his room and played it up loud if he was crying then turned it down softer once he fell asleep...it even put me to sleep a few times..lol!!!!
