preschool/play group

I have such mixed feelings about sending her twice a week to go play with her friends. I know she loves it but I feel so guilty sending her away from me and yet when she is gone I get so much done! She asked all summer when it was starting again...so I need to just let her go and know she is having fun...I know its only 3 hrs twice a week...She insisted on a ponytail (it was the size of my pinky)
