Greetings The persistent red, itchy bumps in your 14-month-old resemble several common conditions like eczema (atopic dermatitis), hives, or chronic insect bite reactions.Eczema often causes dry, scaly, and intensely itchy patches, while hives appear as raised welts that may shift in location.Given the history of allergies and the two-week duration, it is important to consult a pediatrician to identify the specific cause and rule out infections.To help manage the itching at home, you might use cool compresses, fragrance-free moisturizers, or lukewarm oatmeal baths.Keeping your child's fingernails short can also prevent skin damage and potential secondary infection from scratching.

He requires check up and medication probably investigation if not subsiding or the problem is recurrent.

Apply Calamine lotion

Even we are also not sure it is mosquito bite or allergy unless you send the picture over here

This may be due to insect bite hypersensitivity/papular urticaria, allergy, heat rash, or eczema. Recurrent itchy red bumps in this age are commonly triggered by mosquito/insect bites.
