I realize that all mothers eventually feel a sense of sadness when they realize that their babies are growing up. My youngest baby is only 17 months, but I already feel pinges of pain when I think he is losing his "babyness". I sometimes think he looks like such a big boy, but then quickly tell myself that is still just a baby. In these pictures, he looks more mature and he desperately wants to follow the big ones. Slow down, sweet boy, mama isn't ready for you to grow too big just yet!
