Thanks jamakin! I thought I would post again because we found a solution!!!

I did some research into separation anxiety and they recommend playing peek-a-boo and helping baby 'practice' the concept of being left until you return. So today I played SO much peekaboo. We also extended the nightime routine to include 5 mins of extra stories/cuddles before being put down as well as holding her lovey/comfort toy while we breastfed...

So far so good. I hope it helps other people with the same prob.
