Hey Vuvs
I am probably a bit premature in replying but here goes anyway.
My girl just over 4 weeks has been feeding non stop. I went to a private midwife to get help. She recommended a chiropractor. We went yesterday and this is what he said! C sec babies have a higher chance of a mal aliginment of the neck (natural is lower back) and this causes discomfort in baba which makes them stressed and release adrenalin, this in turn messes with the digestive process and voila colic.
Apparently this starting 2 to3 weeks after birth is a big clue!
We had our first session yesterday morning we got a 2 and half hour nap in the afternoon and have just had 6 hours tonight. I can't believe it. He warned us that today would be niggly and from thurs she would be better.
We have a final check up with him on thursday. He was so gentle with her, you would never know he was working on her. I know it is early days and I hope it lasts. But my baby does seem so much happier and more relaxed.
Good luck finding your solution.
