Yes, my daughter was diagnosed when she was 2 months old. She went to therapy in Laurel (14 years ago they were the only pediatric physical therapists around.. I can't remember the name of the place off-hand). At first she went once per week, then once per month until she was about 8 months old. Her head was tilted to the left, her neck muscles were very tight on the left and very loose on the right.
I did exercises with her several times per day, I remember holding her on one leg and bouncing/leaning her to her left, and she would try to lift her head to the right, which strengthened the muscles on her right side. She always enjoyed this as it was just "play" to her.
Twice a day I would lay her on her back and do the left side stretching exercises, by gently pulling her head as far as it would go to the right, while massaging the left side. She didn't like this as much, but I'd try to distract her with singing, etc, but it was never a big deal. I don't remember her crying during it, just fussing.
Have you had your daughter checked for dislocated hips? My daughter was also diagnosed with this 2 months later, when she was 4 months old. I only bring this up because most babies with dislocated hips also have torticollis, they seem to go hand in hand. And it is MUCH more common in girls than boys.
We saw an ortho at Georgetown, a Dr. Delahay, and he was wonderful. If he is still practicing, I highly recommend him.
Good luck to you! I know how scary it is having to deal with this
