Whether your baby’s sleepiness is a precursor to pneumonia should be determined on a case-by-case basis and should not be generalized. Babies sleep longer than adults and need enough energy to meet their growth and development needs. When a baby is paranoid and anorexic, the nutritional supply is insufficient, i.e., lacking in micronutrients, and drowsiness is likely to occur, but it is not drowsiness caused by pneumonia. Infants with pneumonia may not have the typical symptoms of severe coughing and rising temperature due to their poor defenses, but rather they may be refusing to breastfeed and lethargic, so once these symptoms appear, they must be treated by a pediatrician at a regular hospital. It is recommended to keep the room air circulation, room temperature around 20℃ and humidity around 60%, give easily digestible food, and turn and pat the baby’s back frequently to avoid colds, choking and other undesirable conditions.
