H's first day at daycare

We dropped H off about an hour ago for her first day in daycare. It's only for 4 hours, but man, did it hurt. Badly. We met up with the director and went over the paperwork as well as inventoried all of H's clothes and supplies. Once we were done, I handed her over and she started frowning! WHY?!?! DeeJ took her back for a few minutes to say goodbye and she was fine. He handed her back and she started frowning again. She even watched us as we were heading towards the door, frowning and pouting. I can't even stop myself from crying at this point. I feel hurt and devastated. I miss my baby.
