Sounds like she should like it since all her buddies are there. She'll get better about you leaving her. Sarah had a hard time adjusting to her new teacher this year and so on the way to school I started to say "Sarah, I'm going to see my Mrs. Bea" and she'd say "no - my Bea" and then we argue. When we go to the room itself, I'll say I'm going to see my Bea and she'll run to beat me to her Mrs. Bea.
I have to agree, that lunch kit and backpack is so cute. You always have stuff I love. I wish you'd just be a personal shopper for Sarah.
Oh and Sarah is

about her Dora backpack. She wears it around the house, wants to take it everywhere, won't take it off at school for at least the first 30 minutes. She is just like the cartoon Dora with a backpack stuck to her.
