Hello again, Marbles,
I finally got a chance to explore around your blog, and 'get to know' you and your gorgeous girls a little (my display's faulty at the moment, so bit hard to tell, but I think you've got 2 mini redheads there? How lovely!). 
God, watching the Youtube hospital clip of Mabel's breathing really does bring it home how very scary those episodes must be for you to see.
I really hope more effective treatment can ease all her symptoms.
Hard enough for anyone not to want to scratch itchy, inflamed skin, but must be doubly so when you're little and can't fully understand the consequences.
Despite (or because of?) all that, she comes across as a strong and determined little character, and obviously does a lot of fun stuff with her Mum (loved your home Easter egg treasure hunt film. And I think my reaction would have been the same as hers to Castle Ashby's slightly scary giant Easter Bunny!)
Will follow her progress (and catch up with a few of your archive posts soon, too). And, off-topic, I'm proper envious of your kitchen...
