hI, we're going through the exact same thing. I was on the phone to my maternal nurse this morning and she just told me to do controlled crying or CIO ( Cry it out). My little one has been waking every 45 mins - 1 hr for the last 8 nights, but generally about 5 times a night since she was 4 months old.

We went to an osteo today for the first time, and it may be complete co-incidence, but she's been asleep for 2 hours already and i can't believe it!!

I'm also getting her checked out at the GP for any sort of sensitivities - i've a feeling dairy may be as we also have eczema in the close family. And any ear issues too.

Perhaps try osteopathy? hugs to you though - it's sooooo exhausting,isn't it?
