I know it's too late for tonight, but how did it go? My DD always sleeps loads extra with a fever so I probably would've let her sleep from 4:30 either until she woke up, or wake her around 8ish, try a bit of food and then do BT. When she's ill I find timings pretty much go out the window, and I've always hated doing CNs and waking after such a short time! Anyway, just wondering how you got on and hope she feels better in the morning x
