Last few nights DD has woken in the middle of the night screaming "mummy mummy" and when I come, she's initially calm but then says something like "I want a cuddle" or "Where's your red jumper" (I have a very soft red jumper she loves), so I give her a cuddle or tell her the jumper is in the cupboard, and then she absolutely goes berserk. Screaming, crying, completely inconsolable, and it goes on and on, probably for 15 minutes or so? No amount of holding, cuddling, rocking, patting etc will help. I've tried white noise, DH has tried to soothe her. Eventually I'm able to distract her or hold her and she sort of cries herself to sleep. But it's awful! Is this a night terror? What can I do? We're all knackered.
