What to do with myself??

After almost 15 years of having young kids in the home with me most of every day, today we sent our youngest off to pre-K at the Goddard School. Noah was so excited and has been looking forward to this all week. Now I am at a loss as to what to do with my day. Maybe I will paint the living room? Or maybe I will take a nap? Maybe I will go for a long walk? I am sure that my days will fill up quickly, but in the meantime, I am missing my baby...
