Normal pediatric motor development pattern motor pattern.
The total direction of movement development of children is from head to foot, that is, along the head lifting → turning over → sitting → crawling → standing → walking this trend of gradual maturity, the earliest is the movement of the head, the first will lift the head, then will turn the head, later began to turn over, about 6 months will sit, and finally to stand and walk.
Briefly summarized as.

From 11 to 15 months: The child can walk, but has poor balance and often stumbles.
At 15～18 months: The child can stand up independently and walk by himself/herself.
Early detection of brain-damaged children.
Children with high-risk factors such as prematurity, low birth weight, postnatal hypoxic asphyxia, heavy or prolonged postnatal jaundice, early pregnancy with pre-eclampsia, birth control, etc. need to be seen by a pediatric neurologist or rehabilitation physician if they have the following symptoms.
1. Neonatal period (within 28 days of birth).
The infant does not eat milk, does not cry, has difficulty feeding, and has low responsiveness.
