Holding a baby is a foundational habit for emotional stability, attachment formation, interpersonal skills, and the basis of self-esteem.

Oxytocin, a "security hormone," is secreted in large amounts in a baby's brain through physical touch such as back rubs, hand holding, gentle cheek touching, and massage.

The traditional belief that holding a baby too much creates "bad habits" (抱き癖) is scientifically disproven and based on outdated values.

Babies who are frequently exposed to gentle expressions, slow movements, calm voices, and smiles from their parents develop higher empathy, emotional stability, and social skills.
