I went through the same worries with my son last year. He is 10 now and it was a good thing to do. I somewhat wish that we had done it earlier but neither his mother or I wanted to do it. After several attempts to boost calories and get him to eat a lot (and lots of frustration), Parker had a g-tube put it and it really worked out well (or at least it has so far). There are not the limitations on activity as I thought there would be (he played baseball this spring and I was a little concerned when he would slide but there were no problems). There are lots of people who can help with pratical advice. It really helped me out a lot. For my son, the tube is a great idea. I do not see him needing the tube forever...just until he is past needing to grow (30 or 40 or something like that) but then again it gives us some options. Good luck and feel free to PM questions or ask for anything.
