‘怕生’ (pàshēng) literally means ‘fear birth,’ but it actually describes the shyness or wariness that young children or animals feel around unfamiliar people. The character 怕 (pà) means ‘to fear’ or ‘to be afraid,’ while 生 (shēng) here stands for ‘strangers’ or ‘unfamiliar beings’ — not ‘birth’ in the literal sense, though the etymology reflects an older usage where ‘sheng’ implied ‘not yet familiar’ or ‘newly encountered.’

This term is commonly used to describe toddlers who cling to parents when meeting new adults, or pets — especially puppies and kittens — who hide or avoid contact with guests. It’s a neutral, observational term, not judgmental. While humans usually outgrow this behavior, some animals may remain ‘怕生’ into adulthood if not properly socialized. Parents, teachers, and pet owners often use this word to explain cautious behavior without labeling it as abnormal.
