Karen, I love the good news. I have 4 nieces and nephews. They all seem to grow in the summer. My daughter just grew 2 inches over the summer too, she was undersurpressed, so there seems to be no ryme or reason to kids and how they grow. But her endocrologist was very happy with her growth. My dad always says kids grow alot like horses. First they grow tall and thin, then they tend to fill out. And then the process continues. I am glad to hear of your good news!
