Parental genes do not stand out in infants and children, who look slim and pretty in their faces. While growing, however, they resemble up to 85% of their parents' skeletons.
Proper minimum age to wear HEADrang is 4-5. Select S-size product for the infant and choose the chin band depending on the infant's state (pressure, pain, etc.) when wearing it.
For the case of infants, it's more effective to use it repeatedly in a short cycle rather than use it excessively for a long time. Recommended daily use is 30-60 minutes, and a long-term continuous use.
Despite of the shorter daily use than adults, a larger effect is expected for kids, when the bones are flexible and grows faster.
