You are not alone!
47% of infants develop some form of head deformation. 
Ask your doctor about torticollis
Almost 100% of patients with head deformation have some form of neck stiffness or instability referred to as torticollis. (2)
Physical therapy can prevent the need for a cranial helmet
When physical therapy is indicated, it can reduce the risk of severe head deformation by 46%. 
Start Physical therapy as soon as possible
When physical therapy for torticollis is indicated, the process should be started at 7 weeks of age for the best chance of preventing severe head deformation. 
Make sure your child is evaluated by experienced doctors
There is a 1 in 2,000 chance of an infant having a more serious issue than plagiocephaly called craniosynostosis.
