Man I can't imagine what you and the wife are going through, time in the shed will help you a heap (busy hands etc), make sure that your wife gets all the support you can give her,it will get easier to deal with, remember the joy your boy brought to the both of you.
terrible news. nothing can fill the void exactly, but this dumb hobby will help to see you through until youre with your son again.
Very sorry to hear of your loss. Keep your family and friends close to you at this time, it will help.
I've been thinking about you and your boy a lot over the last day or so and trying to put myself in your shoes. The only thing I could come up with was that if I was to lose one of my boys, it would be the worst thing I could imagine. With that in mind, you have just experienced the worst time of your life. From here on it can only get easier and nothing will ever hurt as much for the rest of your life. Little consolation, I know, but you'll get through. My thoughts still with you. Pete
