Aww! She's adorable! The Tea and Tissues thing sounds like a wonderful idea! I'm sure she will do wonderful in school- and you have all the time in the world to help her navigate through her new experiences with school
You will be just fine- it will get better once you get into a regular school routine with her
my room is on the kinder hall in our school...the music teacher is across the hall, & always has a box of tissues ready the first day of school when the parents come to drop off their kinders!
