when do babies start cooing

Babies typically start cooing around 6 to 8 weeks of age, which is about 1.5 to 2 months old. This early form of vocalization consists of soft vowel sounds like "ah" and "ooh," signaling the beginning of language development and emotional comfort. While some babies may begin earlier or later, if a baby hasn't started cooing by 3 months, it is advisable to mention this to a pediatrician. Cooing helps babies practice the muscles used for speech and serves as a way to express happiness and interact with caregivers.
