Kindergarten Registration

I just can't believe I'm signing Jaydon up for KG.  He's 5...5 years old...where did my happy, smiley baby go?  He's ready for big boy school.  This is his second year of preschool and he's the "big kid" at school, because of both maturity and size!  He's excited about going to school all day, eating lunch at school, and seeing his friends all day!  What will this lonely mother do with all of her time?  I have lots of ideas, and I'll have to keep you posted.
