Solid Food Already!?!?

Yesterday Sean had his first taste of rice cerel and he loved it. Granted it was mixed with breastmilk so it wasn't too far away from the normal for him but he still ate every bite of his two servings. He is growing up so fast...I am so happy that he is growing and developing and is such a joy in our lives but I am also so sad that he is progressing so fast. I guess I just want him to stay little just awhile longer. But I have to remember what a joy and blessing children are and to appreciate every stage of their lives for what it is.
