Just an update. This morning W came to do the morning routine with the girls. I was up already in the kitchen with D17 and she said 'Good Morning' to D17, then looked towards me but not at me and said a quiet 'Good Morning' to me and I said it back in a nice tone.
Then I went to my room until she left.
She made a pot of coffee for me, emptied the dishwasher, clipped some coupons from the paper and left them on the counter for me.
