回复：俺来解释一下。按很怀疑自己未老先衰了，连儿子的雪滑冰年龄都记混了。

thank you very much. Your post let me see some hope. My son is just like yours used to be.
I also took him to swim class. He was crying, and refused to get into the water till the end. The fee was pretty much wasted. I can swim, skate, play balls. Yet everything seems so hard for him, especially when I see other little kids who are having fun. He is also a shy kid.
