Thank you for your query.
Though it is common for children to have repeated attack of upper respiratory tract
infection quite frequently from about 12 months of age till about 3-4 years of age, it is always to better to get your daughter examined by a doctor to rule out any persistent cause of infection. I would suggest to get base line investigations done which include:
2. Urine routine
3. Blood sugar random
The anthropological parameters are alright for her age. Continue giving a good balance nutritious diet to your child.
I hope I have answered your query to your satisfaction.
