Thank you for your query on Healthcare Magic.
Frequent or continuous cold
in your child may be due to some allergy
or due to frequent exposure to viruses causing cold.
Observe the child symptoms in relation to his food items, exposure to cold, pollution, and maintain a diary to correlate his symptoms with type of exposure so that it is possible to identify the allergen.
And simple cold and cough
can be treated with symptomatic treatment with oral antihistamines and cough medication and antibiotics are not required most of the times.
And avoid exposure to cold, pollution, plants, pets, and people with cold.
Hope I have answered your query.
