My daughter has had a g-tube for about 3 1/2 weeks now. She is onlly 21 months, so it's a very different experience. I have to say, I can not iimagine how hard it is for your boys. I would be in tears too, if I were them, and I COMPLETLY understand the panic over the blood. We have a panic situation every couple of days as the site heals, then tears, then heals, etc.
I think Jane is the Lady to listen to on this one. (And, of course, the others who responded) THe anti-depressants seem like a good idea. I know that it probably seems like a giant step to take, but then so is the g-tube. It really is life altering, and for me at least, the clinic totally lost site of that fact. Your boys need to know that this IS a big deal, but it's a good thing. Recognize the fact that they are hurting emotionally and physically. It could be that this is the first time they were old enough to really be hit by the realities of cf. Nothing like a tube in your tummy to show you what this disease can really do!
As far as the formula, we are still waiting to see what our coverage will be. But, our dietician did mention that Pediasure has a grant progam that would cover at least part of your costs if we have to do more than 50% out of pocket. Or, something like that. So, ask your center staff, and contact the manufacturer of the formula. They may have a program.
I will keep your boys in my thoughts. ANd you, too. The care and maintenece of the g-tube is NOT easy. I am stressed just wondering if I'm doing things right and wondering if I'm doing more harm than good.
Please post more often and let us know how things are going.
