Dd has never slept through, but this is ridiculous. She is waking up every 15-20 minutes all through the night every night and crying like she has been shocked awake, and can't calm down until I cuddle her. I feel so ill and am so short tempered because of it! It used to be 2 or 3 times a night, but has slowly got more and more frequent. I just want one single unbroken night of sleep-I've waited four years for it!!!
