Can a two-month-old infant use cinnabar for sedation?

Generally, two-month-old infants should not be given cinnabar for sedation.

Cinnabar contains mercury sulfide, a heavy metal that is toxic to some degree. The organs and systems of a two-month-old infant are not fully developed; oral intake, inhalation, or contact with cinnabar may damage the cardiovascular system and central nervous system, causing symptoms such as dizziness, headache, irritability, crying, or sleep disturbances in the infant. Moreover, long-term use of cinnabar can lead to accumulation of heavy metals in the body, which is detrimental to growth and development. Infants this young should not be given sedative medications unless absolutely necessary. Apparent fright in two-month-old infants mostly represents normal startle and embrace reflexes common in newborns. When the baby is sleeping, parents can wrap the infant snugly in a small blanket, even securing the arms close to the body, to recreate the familiar feeling of being in the womb, thereby reducing startle responses. Another reflex, known as the embrace reflex, occurs when an infant feels startled and instinctively extends their arms outward before drawing them back toward the chest. These reflexes gradually disappear with age and are normal physiological phenomena observed in nearly all infants.

In addition, parents are advised to increase skin-to-skin contact with their infants, which helps the baby feel more secure.
