When will i be able to tell if my baby has allergies?

When symptoms start: Allergies can show up at any age. If allergies run in the family, your baby has a better chance of developing them. If your child develops chronic runny/stuffy nose, frequent ear infections, wheezing or prolonged cough (more than 10 days) after a cold or gets eczema, then allergies may be developing.

2 years and up: Most children need at least 2 years of exposure to environmental allergens before becoming allergic to them, especially in the case of seasonal pollens. Therefore, in regards to environmental allergies causing nasal and ocular symptoms these rarely occur in children less than 2. However, food allergies are different and can occur much earlier.

When symptoms start: Allergies can develop at any age. In infants, the most common manifestation of allergic is a chronic, itchy skin rash called eczema. Infants can also develop asthma with a chronic cough or wheezing. Most chronic nasal symptoms in infants are due to infections and not allergies.
