Question
A parent is concerned about their 71-day-old baby who has not yet been able to laugh when amused and is asking whether medical assistance is needed.
Answer
Every baby has its own personality and way of expressing emotions. Even if your baby has not yet started laughing frequently, as long as they are in good spirits and react to external stimuli, there is usually no need to worry excessively. Most babies begin to laugh out loud around three months of age, so if your baby occasionally does laugh, it is typically normal. It is recommended that parents interact more with their baby, engage in play and conversation, which may help increase the baby’s laughter. If parents still have concerns, they can consult a professional medical staff.
