The state of being excessively fatigued in infants, leading to increased irritability and difficulty settling, often manifests as crying, fussiness, and resistance to sleep. An instance of this would be a baby who misses a scheduled nap and subsequently struggles to fall asleep later, exhibiting heightened distress signals.
Addressing infant fatigue is crucial for promoting healthy sleep patterns, regulating emotional stability, and fostering overall well-being. Historically, various techniques, ranging from swaddling to rhythmic movement, have been employed across cultures to soothe distressed infants experiencing this condition.
