DD started daycare this month and drop offs are ways tear filled. My kid is very self aware and we cannot lie to her. she usually asks for me to stay with her for a little bit and when I leave she starts to cry. My sister said to say goodbye at the door and go. I don't know what to do. Any advice would help.

She only goes 2 days a week but will be transiting to full time for a month whe our nanny is recovering from surgery.

She does well in school, plays and helps.
