R.C.
Very normal. I teach kindergarten and I always talk about this at our parent meeting before school starts. Usually the kids are SO excited that for a week or two they pop in the room, big smiles. However, on occasion, after a couple of weeks, reality sets in. They realize, "This is every single day..." And really, anyone who had a choice between staying at home in pjs or getting up and going...well, we know what the choice would be. :) Usually they settle into the routine. The best thing to do is smile, wave goodbye and walk away, hard as it is. If you stay and comfort, it is actually more unsettling to the child usually. Good luck!
