I can't remember if someone else already mentioned this, but when you first see his ostomy bag, remember that the hospital-supplied version is often see-through and crinkly. The see-through part is great when you're in the hospital so the staff can see what a patient's output looks like, but at home, most people get an opaque version that leaves a little more to the imagination and doesn't make so much noise. His bag will probably have a straight, simple clip; there are other clips that curve to your leg to be more comfortable, and bags without clips (either disposable ones without a drain or a drainable version with a Velcro folding closure).
A video to get trained on the bag?? You two will do great!

Mom, you can go the hard way if you want, but the easy way is much easier. ~my 3yo
