I went to your facebook and checked your photo with 60D and 28mmF1.8USM. I like how you photo your wife and son. Especially some of the photos require luck and timing to take pictures.
From the picture I guess you live in Taichung. Am I right?
60D is a really nice camara body with good high ISO performance. After seeing your pictures I am sure my 550D is not as good as your 60D. However, you do have a good sense of placing your son in the pictures.
Your kid and wife are lucky to have you. I am sure you will capture a lot of good memories for your family.
