My baby boy is growing up :(

K I am having real issues the last couple of days, because my son (my middle child and major mamas boy) is growing up. Yesterday in the mail I got the paper to tell us when his kindergarten testing is, and when we will meet his teacher. I knew it was coming, but I am still sad that my son is at that stage. He's going to be gone more often, and I can't keep him right here with me anymore :( Then today he went with a friend to McDonald's to have a lunch/playdate, and when he came home he asked if he could sleepover at that friends. He has had sleepovers at family members houses, but this will be his first sleepover at a friends house. It's right across the street from my house, but I am just not quite ready for my baby boy to be so grown up and not need me as much!
