Introduction
It is generally normal for a one-and-a-half-month-old baby to suck their hands. After birth, as the baby's body develops, the nervous system gradually matures and upper limb movements become increasingly purposeful. At this age, babies typically have normal brain development and progressively mature neural control of the upper limbs. Hand-sucking is a manifestation of the oral stage, through which babies explore the outside world. Therefore, hand-sucking in a one-and-a-half-month-old baby is considered normal.
It is generally normal for a one-and-a-half-month-old baby to suck their hands. The detailed explanation is as follows:
Under normal circumstances, after birth, as the baby's body develops, the nervous system gradually matures and upper limb movements become increasingly purposeful. A one-and-a-half-month-old baby usually has normal brain development, and the nerve control of the upper limbs is progressively maturing. Hand-sucking is a manifestation of the oral stage, during which babies explore the outside world through their mouths. Therefore, hand-sucking in a one-and-a-half-month-old baby is considered normal.
Hand-sucking can help promote intellectual development and enhance coordination among the hands, mouth, and eyes. Parents are advised not to intervene excessively. Instead, they should frequently wash the baby’s hands and maintain good hand hygiene to prevent ingestion of dirt or harmful substances that could cause physical discomfort.
