My baby is one year 8 months old boy Every quarter he gets cold cough i dont know why after every 2 or 3 months he gets sick plz suggest

A. hi it happens because of low immunity. give citrus fruits ,green veggies , nuts , pulses etc to your child. give Turmeric milk once in a day keep your child well hydrated give sunlight atleast 20 minutes a day maintain good hygiene using Babyhug multipurpose cleaner.
