Firstly - apologies in advance for the long post! Our DD is a pretty happy, good-natured baby during the day and only really cries for the usual reasons (basically hunger, tiredness, or being held for too long by someone who isn't mummy). She generally goes to bed okay, but since she was very little (6 weeks or earlier) she's often (though not always) woken up crying between 10 mins and an hour after first being put to bed. We used to be able to calm her either by feeding, cuddling, or shushing (or a combination of the three) and although the crying was more than grizzling, it was never full-on distress crying.
Recently, though, she's been waking up absolutely screaming - as though she's really frightened or in terrible pain, and instead of once, she does it three times in the space of an hour or two, and then often again around 11pm (she goes to bed at 9pm). Whereas before my DH could soothe her with a cuddle or a bottle (she is mixed fed), now the ONLY thing that will soothe her is my breast, and even then sometimes even when the nipple is in her mouth she'll carry on crying (which she's never, ever done before - previously as soon as she had a boob, she'd instantly calm down).
I know this might just be random baby behaviour which she'll stop one day and we'll never know why she did it, but I just wondered if this had happened to anyone else and if so whether there's anything we can do to stop it/help her? It's so horribly distressing - I hate hearing her cry (what mother doesn't?), but this type of crying is so awful it makes me sob myself and leaves me traumatised. I just don't know where it's come from and why she's so upset...
