My Baby Boy is Registered for Kindergarten

I cannot fathom how Caden is old enough to go to Kindergarten.  It seems like just yesterday I was swaddling my 5 lb 13 oz baby boy in his Miracle Blanket.  Some how though, he is 5 and it's time.  I took him Friday to the girls' school along with our packet of completed (yea) paperwork.  We met with the school secretary, the kindergarten teachers and the school nurse.  We saw lots of Moms I know from the girls' class with lots of little 5 year old boys.  Caden isn't too excited to be starting school.  He's also not too excited about riding the bus.  I'm a little worried about the initial break, but eventually I think WE'LL BOTH be okay!
