Growing up so fast!

It never ceases to amaze me, each and every day, how fast Spencer is growing up. The other day Chris wanted to let him ride on his shoulders, to which I shrieked: NO! He's too little. Luckily when I have my moments like this, Chris doesn't really listen and goes ahead and does it anyway. Because obviously, he is not too little for such fun!
In fact, he loved it. How dare mommy try and deny him this fun!
