Jo - My oldest, Jaz, is asthmatic. She was just 2 when they diagnised her. She had 5 chest infections in 4 months & the last one triggered the asthma.
So much fun. I had an allergy blood test done on her. She's allergic to mould & mites. Loads of fun. Mould is the worst. If there's any around anywhere in the house, or someone elses house she doesn't stop coughing.
Then during winter any running around she does sets it off.
I hope Caitlins isn't too difficult to manage. I've had times when the ventolin hasn't helped & I had to take her outside into the night air & sing to her & rock her to calm her down.
