My son has small patches/bumps on his legs, what should I do?

It is possible that the child is experiencing an allergic reaction. It would be good to check for any new soaps, laundry detergents, or new items in the house that could be causing a reaction. Keeping a journal of activities and foods consumed can help identify the trigger. Using a fragrance-free cream like Aveeno or Glaxal Base may provide relief and can be applied as needed throughout the day. If there are any other symptoms or concerns, it is recommended to seek advice from a pharmacist or healthcare professional.
