A.P.
My son was born forceps-assisted, which created problems for his neck. Fortunately, I had a doula for his birth, and she recommended chiropractic, which I would not have thought of! People think it's weird, but it really works, and is so gentle. The chiropractor just lightly taps with one finger when it is a baby he or she is adjusting. This corrected the problem for my son. I know others in similar situations who didn't get similar advice-they did pt, and had to buy expensive devices, and it sometimes took a long time and lots of money to correct the problem. My son did have to go to the chiropractor a few times, but I was so glad I did it.
The chiropractor I went to is in Montclair. If you're anywhere near, shoot me an e-mail and I can give you her contact info--she worked on my son when he was five days old, and works on newborns and babies all the time. And she's also a nurse.
Best wishes for health for your family!
