Infants may exhibit symptoms such as lethargy, insomnia, and palpitations when they lack certain minerals. To alleviate these symptoms, consider supplementing with a multivitamin or 21 Gold Vitalis and increasing the intake of water and fruits. In treatment, you can use wind-dispelling oil for massage or apply warm towels. Additionally, changing the infant’s sleeping position, such as allowing them to sleep on their stomachs, may help alleviate symptoms. However, be mindful of the mattress hardness to prevent suffocation. Typically, these symptoms disappear on their own by the time the infant is four to five months old.
