Both of my kids had colic. I agree with Molly- pump and let hubby feed.
My kids both had formula, I was unable to breastfeed, and we found that they weren't lactose intolerant, just lactose overload. We switched formulas to a lactose free one and it made a HUGE difference, so once again, Molly is right on track by suggesting you check your dairy intake.
One night, I was just like you, ready to lose it. I called my mom in tears and she asked if I was holding her. I answered yes. She said put her down, she's tired of being held and bounced around. Three minutes later she was sound asleep.
You are most likely at the peak of colic right now and hopefully she will start "settling in" with her new little body, but gosh, I feel for you. Been there! It is SO IMPORTANT that you get away from it for awhile, your husband really does need to conquer his fear of this and give you a break, even if all you do is go walk around the block (with your son!). Even little breaks away can make such a difference.
Good luck (hug). Now go call your mom and rip her a new one. This is all her fault! :) ha ha ha
