Sometimes they really do love each other. Although...to be honest, I never know if Clark is really hugging him, or just trying to see how hard he can squeeze him.
It astounds me how big Harry is. But, every time he starts to finally catch up to Clark, Clark decides to have another growth spurt just to keep ahead. I love to watch them play together, when I am lucky enough to get them to play together. I love having two little boys!
