Is It Normal for a 4-Month-Old Baby Not to Laugh Out Loud?

Dear parents, as new caregivers, you may eagerly anticipate every giggle from your baby. A 4-month-old baby not laughing out loud is often a normal developmental phenomenon. According to guidelines from the American Academy of Pediatrics (AAP) since 2020, audible laughter typically emerges between 3 to 6 months, but individual variations are significant. Some babies might laugh vocally earlier, while others need more time. This does not indicate a problem but reflects your baby's unique developmental rhythm. Stay patient—your loving care is crucial for their growth.
