This is quite out of character - my four week old DD has spent the whole night tonight awake, and crying incontrollably, even when being cuddled, which is usually a sure fire way of settling her. She's quiet if I give her a dummy (which she can usually take or leave) but starts screaming and wriggling about again the minute it falls out! I've tried all the usual bedtime stuff, swaddling, white noise, she's changed, fed, burped etc.., she's been awake now since 9pm, give or take which I know can't help... Any insights or tips?!
