Molded helmet
An infant's skull is easily molded. If necessary, a molding helmet might be used to help shape a baby's head. The helmet is worn at least 23 hours a day during the treatment period — often several months or even longer.
If your baby's head shape is still uneven by age 5 months, your baby's healthcare team might suggest a molding helmet or band. These are custom-fitted devices adjusted weekly as the skull shape changes. The device is worn for all but 30 minutes a day.
Molding helmets seem to work best for babies ages 3 to 6 months old. At this age, changing the shape of the head may take about 12 weeks. Changing head shape in children up to age 18 months is possible, but the process may take longer.
