Patient's question:
The child mostly keeps their thumb inside their fist during the postpartum period. At two and a half months, sometimes they still press their thumb under their index finger. Sometimes their thumb sticks to their index finger when they open their palm, and other times their palm is fully open. When sleeping, their thumb does not retract. There is no internal or external rotation of the arms. Head control is still a bit shaky.Doctor's answer:
Within the first year, the development of infant motor skills primarily manifests in the development of hand movements and upright walking. Specifically, from lifting the head to rolling over (3 months), sitting up (6 months), crawling (8-9 months), standing (1 year), and then learning to walk (1 year and 1-2 months), hand movements also gradually develop into eye-hand coordination. This progression moves from unconscious touching (3 months) to deliberate touching (5 months) to the development of grasping movements (after 6 months).Guidance: The child's nervous system has not yet fully developed. Many primitive reflexes still remain. His reflexes are a primitive reflex, which is a normal phenomenon. You can have a pediatric checkup as well.
