As title suggests, I want to know how 'rare' it is for an under 7 to suffer some level of hayfever. I have a 20 month old girl and for the last week/10 days she has been streaming at the nose, coughing and rubbing her eyes. No other symptom. She did push through a tooth last week which I put it all down to but it hasn't gone away. Spoke to a health professional who told me it's 'rare for an under 7 to suffer hayfever' and then googled it and found out that is the NHS's party line onthe subject so I wanted some real life opinions please?? In your experience can a toddler develop hayfever?? Or am I barking up the wrong tree?? Thanks in advance.
