Environmental adaptations can control posture in strollers, car seats  and swings (using U-shaped neck pillow or blankets to hold neck in neutral position)
Passive cervical rotation (much like stretching when being supported by a pillow, have affected side down)
Position infant in the crib with affected side by the wall so they must turn to the non-affected side to face outPhysical therapists often encourage parents and caregivers of children with torticollis to modify the environment to improve neck movements and position. Modifications may include:

Adding neck supports to the car seat to attain optimal neck alignment
Reducing time spent in a single position
Using toys to encourage the child to look in the direction of limited neck movement
Alternating sides when bottle or breastfeeding
Encouraging prone playtime (tummy time). Although the Back to Sleep campaign promotes infants sleeping on their backs to avoid sudden infant death syndrome during sleep, parents should still ensure that their infants spend some waking hours on their stomachs. Microcurrent therapy
A Korean study has recently introduced an additional treatment called microcurrent therapy that may be effective in treating congenital torticollis. For this therapy to be effective the children should be under three months of age and have torticollis involving the entire sternocleidomastoid muscle with a palpable mass and a muscle thickness over 10 mm. Microcurrent therapy sends minute electrical signals into tissue to restore the normal frequencies in cells.
Lateral neck flexion and overall range of motion can be regained quicker in newborns when parents conduct physical therapy exercises several times a day.Physical therapists should teach parents and guardians to perform the following exercises:
Stretching the neck and trunk muscles actively. Parents can help promote this stretching at home with infant positioning. For example, prone positioning will encourage the child to lift their chin off the ground, thereby strengthening their bilateral neck and spine extensor muscles, and stretching their neck flexor muscles. Active rotation exercises in supine, sitting or prone position by using toys, lights and sounds to attract infants attention to turn neck and look toward the non-affected side. Stretching the muscle in a prone position passively. Passive stretching is manual, and does not include infant involvement. Two people can be involved in these stretches, one person stabilizing the infant while the other holds the head and slowly brings it through the available range of motion. Passive stretching should not be painful to the child, and should be stopped if the child resists. Also, discontinue the stretch if changes in breathing or circulation are seen or felt. Stretching the muscle in a lateral position supported by a pillow (have infant lie on the side with the neck supported by pillow). Affected side should be against the pillow to deviate the neck towards the non-affected side.
