DD can self settle and used to be a great wee sleeper up until about six weeks ago (coincidentally right after her mmr). Since then she has taken to waking up at random times in the night and crying on and off for ages. She doesn't cry constantly but will cry for a few minutes then go quiet for a few minutes then start again.
I haven't a scooby what is going on!! DS was a terrible sleeper as a baby and we had to resort to controlled crying with him which was awful but worked in two nights.
As DD can self settle and used to sleep through the night no problems I haven't a clue what to do.
Any suggestions?
