Hi ceri,
I agree that you seem to doing really well with settling your dd into nursery, it's often much worse for the parents, who have the image of their upset children in their head all day, when actually, their child is playing happily, or at least, having a cuddle and watching everyone else.
I think it is good that you are increasing her days to 1.5, as for some children, the gap between sessions can make a difference to how quickly they settle. (I am a nursey nurse so have seen this from the 'other side'.)
As for her being a cling-on, I have found this is common with children who start nursery etc.. and passes as they make the connection that you always come back. Maybe you could try saying 'Mummy's going to the kitchen/wherever, I'm coming back' whenever you have to leave the room at home, and then come back 30 seconds later, then increase the time you're away gradually. (you may already do this!)
I did find that telling an upset nursery child that mummy/daddy had gone somewhere specific, like the shops or in the car, something very simple they could understand, and repeating this over and over, really helped with some children. Parents would then reinforce this when they were leaving.
I'm sure she will settle down soon, both at home and nursery. Please feel free to post any other questions you may have, there are loads of people who have been through this on mn, plus nannies/childminders/nursery nurses with heaps of experience.
