DD has always been a good night time sleeper (not smug at all, as she has always been a horrible day-time sleeper!)
She goes down around 8pm and for about four months has been doing 10-11hr stretchs.
The last three nights she has woken up around 11.30pm-12am in absolute hysterics, proper shuddering, inconsolable crying. She never cries like this - she cries with teething pain, but never this bad. At first I thought the very bad nappy rash she has been suffering from for the last four days was causing her pain, so I have picked her up, cuddled her and changed her nappy, but the nappy rash has cleared up and the night wake-ups have continued.
She usually falls asleep in my arms after about half an hour of rocking and shhing (continuous crying) but can start again when I put her back in her cot. I just have to make sure she is properly asleep before I put her down.
Does anyone have any ideas what this might be and if I should be worrying? I struggle to get back to sleep afterwards as I am so stressed out and so worried about what is causing her this distress and I have been really snappy at DH because I feel so helpless.
Appreciate any help or advice.
