Hi m Mrs vasumathi, welcome to Health care magic forum. If your baby is getting cold
from the age of less than 1 year, it is not a problem, he will be cured of it before the age of 6 years. If it started after the age of 1 or 2 years, it is critical and could be dragged for life.
In the latter case it is due to allergy
and caused by foods, or external allergens like, dress, soaps, dusting powders, etc.
You can find out the things for which the child is allergic, by noting every thing he uses say soap, powder, and foods and drinks he take, and try to find out the things he used before the day of starting infection. Next time if the things he used are same you can avoid them , to avoid cold attacks.
Ofcourse treatment remains the same always, there are new drugs available now for preventing the severity of the allergy, as MONTELECAST. which can be used with promising results.
Wishing for a quick and continued relief to the baby, and thanks for calling.
