For the 4th time this week, I noticed that my 20-month old had blue lips (or around the lips) sometimes with cold, pale/purple-ish fingers/toes. Twice this happened when she woke up in the morning, and twice during the day. She was indoor everytime this happened. It usually lasted for 10-30 minutes. When it happened during the day, she was absolutely normal - laughing, playing. When it happened in the morning, she did seem not quite her normal happy self (but not crying).
I took her to the GP who didn't check anything but did give me a referral because of "parental anxiety". (She said she was sure it was nothing but how could she know if she didn't check anything!)
I looked up the NHS Direct website and it says 999 + ambulance immediately. I am now quite confused as to what I should do if this blue lips happen again and it's before I get an appointment with the hospital. Shall I bring her to A&E?
