Why babies make cough-like sounds In babies, a cough-like sound is often less about "fake coughing" in an adult sense and more about early vocal experimentation. Infants practice blowing, squealing, throat-clearing, and short forced exhalations as they discover what their…

Babies sound before they speak From the first days of life, infants produce a surprisingly wide range of sounds. Some are reflexive, such as brief grunts during sleep or effortful squeals during feeding; others are more clearly social, like cooing…

What does “witching hour” mean in babies? Witching hour describes a recurring period of heightened crying or irritability, commonly in the late afternoon or evening. The episode may last from minutes to several hours. Some babies cry, grimace, arch, pull…

Why crying may peak in the evening Many babies have a predictable period of increased crying or fussiness toward the end of the day. The pattern may begin in the first weeks of life, become more noticeable during early infancy,…

Understand the Post-Crying Stress Response During intense infant crying, a caregiver may experience sympathetic nervous system activation: a faster heart rate, muscle tension, shallow breathing, sweating, gastrointestinal discomfort, and heightened vigilance. The brain is interpreting the sound as an urgent…

Why Repeated Crying Feels So Overwhelming Infant crying is an evolutionarily salient acoustic signal. It is difficult to ignore, can trigger rapid autonomic arousal, and often continues despite feeding, changing, holding, or rocking. When the signal repeats without an obvious…
