My DD is 19 months old and has slept through for 16 of those. But, recently, she has started waking at about 11pm crying, when we go in to comfort her, just the fact that she's seen us winds her up more. We go to pick her up & she forcefully pushes us off. IF we manage to calm her, we put her back in her cot... half an hour later it happens again! She's not hungry, thirsty, wet, cold, too hot.. We considered night terrors, but EVERY night is abit weird. There's been no change to any daytime routine/ food.... so why?
