I have a 15 week old son with Torticollis. My best friend is a pediatric OT and was the first to really take notice of it as a problem. I took him to his 2 month check up the day after she metioned it to me. The Dr. noticed it also. He tilts his head to the right. The Dr. recommended turning his head side to side and holding for a few seconds. Your baby may cry because of the tight muscles. I am sure it hurts but I know it is necessary. Because his head is always turned to the right when he sleeps, he has a bald patch there and also his head is flatter. My Dr. said that as the skull hardens the head will start to shape itself but if I do not work with my son daily it will remain misshapen. It may never be perfectly round but with streching it will have a better chance to round out. My friend the OT actually took the strectching one step farther. She has shown me stretches that need to be done several times a day. The include pulling the right shoulder down and pushing the neck away from it, pulling the neck away from the body, laying him on his side so that his head is looking straight then holding the head still twisting the body so he rolls onto his back. These really hurt in the beginning but it has loosened him up some. he can now turn his head to the left with no problem but he still sleeps with his head to the right. One stretch I can do that he doesn't notice is to hold your baby on his side facing away from you. Put his neck in the cradle of your elbow with his arm against your body. You can use your upper arm to strech the neck. This is what works best for me. As far as slow development I have to wait and see. He is rolling over one way and sits with support just fine. So far I have noticed tummy time is very difficult for him. He flails his arms to the side instead of using them for support of his upper body. He also looks straight down instead of laying his head to the side. I again consulted my friend. She suggested hanging his upper body over a boppy pillow or rolling up a blanket to put under his armpits when he is on the floor. This will help to strengthen the neck more and keep his arms forward. Maybe some of these ideas will work for you. The key is do them regularly, several times a day. I was told that if the stretches are not done it can cause development delays, vision problems, and permament flat head.
