Isn't he too young????

Mason's had his first day of preschool. He, of course, loved it. He loved playing with the kids and the whole idea of 'school'. He was so excited to get his backpack on and head out the door. He sees his school from a distance and will start cheering, 'SCHOOL, SCHOOL, SCHOOL' at the top of his lungs. He's so ready for it. I, of course, sat in the car and cried after I dropped him off. I really wasn't expecting that. I mean.., Mason is such a active, busy kid. He's constantly on the go or thinking of what he can get into next. I've been looking forward to mornings with just the girls and now here it is and I'm sad about it. I know he needs the stimulation and will thrive in preschool..., but can't a mom just want her little boy to stay little just a touch longer. Preschool marks the start of a new chapter in his life. He'll be in some sort of school now for years to come. He's getting so big.., so fast. I know I say that all the time.., but at times it seems like his life is flying by. Though I'm excited for this phase in his life, I still at times miss my baby boy.
