My 2 year old daughter has many allergies; egg,dairy, nut and sesame. Although initially very difficult we have adapted and apart from a couple of severe reactions life goes on as normal..however this weekend she had a cold and at my nieces birthday party she suddenly became incredibly asthmatic. So much so she could not even talk. I gave her piriton and some of my ventolin and an hour after we left (hastily!) the wheezing had stopped...apart from the odd wheeze she has not showed any signs of asthma before this..any ideas what might have triggered this? there had been a cat living in the house a few years before but my daughter tested negative to cats last week. The house smelt of smoke to me (although my mum could not smell it) and it was an old house that i think has had damp problems (mould?)..It was very frightening but don't want to over react as the only time this had happened...guess i need to brace myself for the onset of allergy..at least she has pretty much grown out of her eczema already..any tips/advice would be much appreciated
