My baby is not a baby anymore

Today was Cole's first day of Preschool. When we got to school he tried telling me he didn't need me to walk in with him. Little does he know he still needs me! Well... maybe it's me that still needs him to need me. It was hard dropping him off. How did he get old enough for school already? We are blessed to be in Mrs. Purcell's school. I know she will love him and take care of him.
