It is common for babies to develop small bumps on their skin, especially in areas like the neck and chin. These bumps could be due to heat rash or other minor skin irritations. It is important to keep the baby's skin dry and cool to prevent these bumps from reoccurring. Using a gentle moisturizer can also help in healing the skin. If the bumps persist or if you notice any other symptoms, it would be best to consult with a healthcare professional for further evaluation and treatment.
