Hi J., I went through the same thing with my son who is now seven.I will never forget it! He turned out to be colic. ( even know they say breastfed babies have a slim chance)Try being strict on your diet. My some never spit up,so reflux was ruled out, He was a healthy eater , but after he ate it was horriable. I would hold him face with my arm around his belly or i used one of those baby carriers, which was a life saver. It definately sounds like colic ,the doctors would never say that to me , he just has a little gas and i would think i was going nuts. So try to watch what you eat ( no foods that give gas beans, brocc., some dairy) I cut alot of food and it helped. So did running the vacuum, He would sleep with that at nap time. Hope i helped you some what. Kristin P
