I addressed it right away and then sent a follow up email to about an hour afterwards her saying that if in a week or so she was still very anxious then she should look for a place where she feels more comfortable leaving her little one. In the end I want my clients to feel comfortable dropping off their child in the morning. I'd rather her be comfy somewhere else than anxious with me.
She said she was satisfied although I feel like the relationship has changed overnight.
I have great relationships with my parents. This is the first problem I've ever had and just found it so odd I needed second, third and, fourth opinions.
