Well here's the update.
Last night I tried all your suggestions, covering up, not making a fuss when going out, saying no second time she woke and what a result
Our little darling slept from 10.30pm until 4.45am, I would have usually been on my third trip out by then! She then settled until 5.45 and started barking I told her no and after a few mins she stopped until my girls got up at 6am.
Fantastic we are all feeling so refreshed and hoping for the same again tonight.
