baby is five months old doing bubble like splitting from mouth...why this is happening.kindly suggest

A. Babies blowing bubbles and occasionally spitting up can be normal behaviors, especially during the early months. This can be due to their exploring their mouths and learning to control saliva. However, if the spitting up is excessive, associated with discomfort, or if you notice any signs of distress, it's advisable to consult with a pediatrician to rule out any underlying issues like reflux or feeding difficulties.
