All

Inclusion criteria

Inclusion criteria: The target population for the cranial measurements is 4 months, 1.5- and 3-year-old children undergoing infant health examinations. The caregivers (mainly mothers) of the children who can understand Japanese will be asked to answer the questionnaire.

Exclusion criteria

Exclusion criteria: Any disease or complication related to the cranium that is being seen.

Design outcomes

Primary

Measure	Time frame
cranial deformation rate(4 months, 1.5 years, and 3 years of age): Index of cranial asymmetry (CA), cranial vault asymmetry index(CVAI) and so on, by 3D scanner.	—

Secondary

Measure	Time frame
1.Physical measurements and conditions at the time of delivery of the child: The conditions at the time of delivery (number of weeks of gestation, mode of delivery, sex, birth weight, special notes at the time of delivery, etc.) will be determined from the Maternal and Child Health Handbook. In addition, physical measurements at the time of health examination and risk factors for orientation (birth order, nutritional method, cervical dystocia, hip opening/closing restriction, etc.) will be identified. 2.Sleep-related information: The Japanese version of the Brief Infant Sleep Questionnaire-Revised (BISQ-R) will be used to ascertain infants' total sleep time, nighttime and daytime sleep time, number of awakenings and awakening times, and caregiver responses when they fall asleep. The BISQ-R is used to ascertain the infant's total sleep time, nighttime and daytime sleep time, number of awakenings, and the caregiver's response to sleep onset. Questionnaire with 7 items related to family background and 33 items related to the child's sleep status	—
