niggle - toes with chilblains are very painful. Poor love.
When I first read your post it didn't register with me how young your dd is.
My dd was diagnosed only last year in the prolonged cold snap, at age 10 and I queried why it had suddenly erupted so badly. I was told that younger children do not seem to suffer from Reynauds but GP couldn't say why.
If your DD gets any alarming symptoms do not hesitate to go to the GP and don't be fobbed off. I was lucky that my GP was so kind.
I felt so ridiculous bringing dd in every day for about a week with different rashes and lumps all over her. DD was understandably frightened and actually asked me if she had cancer which made me gag with tears and terror. I collapsed in a heap of tears at GPs and she reassured me that Reynauds is just the body crying out in panic because it can't cope with temp changes and extremes - just like I was crying out right there.
As your dd gets older, make sure nursery, schools, clubs, relatives, neighbours, friends etc are all aware of the symptoms in case it comes back. As I said before, my dd's school are brilliant.
I encourage my dd to be a tough little bird and to do all sorts of sports and spend loads of time outdoors but I am always on the lookout for signs of problems. Don't restrict her life, just learn to help her manage it.
Good luck.
