Niece with a terminal infection

I'm fairly new to this site so many people here don't know what my wife and I went through last year. We lost our 4 1/2 year old son to brain cancer on July 24th 2013. I'm not a religious person but if heaven does exist, I'm sure Owen just made a new friend. They are the same age and I'm sure will have a wonderful time playing together. There are no words to express the deep sadness over the loss of a child. Just know that there are a lot of people thinking about you and your family.
