Yes, I had a cranial osteopath for Sam, who had awful colic, I also tried the chiropractor but didn't find that as good.
With the Cranial, I did see an improvement with Sam. It sin't a miracle cure, but does, in my opinion, put them back in balace. After the first session they'll be really sleepy in the day and then either have a really good night or a really bad night - it tends to be one or the other. I took Sam for 3 sessions and then he was ok by 10 weeks old. It makes alot of sense, especially with forceps babies. Make sure you go to one that specialises/has alot of experience with babies.
