Is This a Phase?

Ava...what am I going to do with you?!? She laughs every time I say that, but I am not always joking! I want to be the best mom that I can be, I want my girls to love to be with me and be confident without me, and sometimes I think we are close to that goal. And then the great back-slide....now Ava lingers a little closer when I drop her off at daycare. I walk her to her class, I kiss her head, then she grabs my leg, "Mommy I need a hug"..."...a kiss..." "...give me another hug..." This could go on forever if I don't sort of scoot her into her classroom! I originally thought this was just a production more for my benefit than hers, but one of her teachers told me that after I left yesterday, Ava cried for the first time in class! She has been at the same daycare for almost a year now...I don't really know what is going on.
It doesn't stop there, at church now she wants to come with me to "mommy's class" and not go to Sunday school. She doesn't even want to go to grandma's house if I am not going to stay with her! Ava...what am I going to do with you?!?
