Hay fever (seasonal allergic rhinitis) typically develops in children aged 2 years and older, because it takes time for the immune system to become sensitised to pollen. However, in rare cases, symptoms can appear in babies younger than 2—especially if there’s a strong family history of allergies.
Symptoms in Babies and Toddlers
Common hay fever symptoms in babies include:
- Runny or blocked nose (clear mucus)
- Sneezing
- Itchy, red, or watery eyes
- Coughing (especially at night)
- Irritability or disturbed sleep
Note: These symptoms can overlap with colds or other allergies (like dust mites or pet dander), so diagnosis can be tricky in very young children.
Triggers
In the UK, hay fever is usually triggered by:
- Tree pollen (March–May)
- Grass pollen (May–July)
- Weed pollen (June–September)
Managing Hay Fever in Babies
According to the NHS and UK allergy experts:
- Keep windows closed during high pollen counts, especially early morning and evening.
- Wipe baby’s face and hands after being outdoors and change clothes to remove pollen.
- Use a cool, damp cloth to soothe irritated eyes or noses.
- Avoid grassy areas during peak pollen times.
- Consult your GP or pharmacist: Some antihistamines are safe from 1 year old, but always check suitability for age.
Here’s a list of safe hay fever treatments for toddlers in the UK, based on NHS guidance and expert advice. Always consult your GP or pharmacist before starting any treatment, especially for children under 2 years old.
