I am pleased to post that while he did wake up at 12am again I was able to resettle him without feeding him. He did have a cry/grizzle but it would have been 5 mins at the most. I left him to it and went back to my bed. Then he woke up at 4 am, I did feed him and slept the rest of the night but at least for the last 3 or 4 nights we have cut out the 12 am feed hoping he keeps this up and stops waking for this feed altogether
