How do I make my baby laugh?

If you are concerned about your baby not laughing or showing a lack of response to stimuli that typically brings a smile or laugh, it is important to consult a pediatrician. A baby's ability to laugh and smile can be an important indicator of their overall development, and a doctor can assess if there are any underlying concerns or if the baby is simply developing at their own pace. Factors such as age, temperament, and the environment can impact when a baby starts to laugh, so it is best to discuss any concerns with a pediatrician.
