I agree, no reason for her to nurse at dc. This is different but I had a parent that would take 5-10 min to say his goodbyes in the morning. Taking me away from the group, I didn't like this. So I wrote a general note to all parents in my daily report asking to say their goodbye before coming to the door. It took a second reminder but he's much better now. I don't think you should give too much thought about what she thinks, you're doing what you need to do to make sure your business runs smoothly. Nothing wrong with that.
