Kids grow up too fast!!

I can't believe how fast time flies when you have kids. I feel like Charlie was just a baby and now I feel like he isn't even a little boy anymore! He is completely potty trained, he is signed up for swimming lessons and preschool, and now he rides a big boy bike!! He and Macie are growing up way too fast!! I wish I could freeze time and just enjoy these kids at their stages a little longer.
