Small bumps appearing on a baby's body can be a common occurrence, and often resolve on their own. It is important to consider various factors such as heat rash, eczema, allergic reactions, or dermatitis when trying to determine the cause of these bumps. If you are unsure, it is recommended to consult with a pharmacist who can provide guidance on the appropriate course of action. Additionally, reading up on skin issues in newborns can provide valuable insight into potential causes and treatments.
