Sharing our struggle

I know that when you have an allergy or sensitivity to a food, you simply stay away from the food and all is well, right? It really isn't that easy, as some of you may know.
In our house, we have been attempting to be Gluten free/Dairy free for several years. I say attempting because as much as I know we need to eat this way, I get frustrated sometimes with the difficulties and financial challenges of sticking with it. Sometimes I just want to drive through McDonalds and be done, you know? So, I have been going through the McDonalds phase again. I would say we have been eating Gluten/dairy on and off for about 2 weeks now, but more on than off.
The results? My son is back to having regular, repetitive twitching, sleeping disturbances and bowel issues. He is also back to having issues with sensory overload, mostly to noise.
My daughter is back to having bowel issues and as for myself, I am having skin issues (I break out on my face and look like I have Rosacea when I eat gluten).
So, as of two days ago, we are back to Gluten/Dairy free 100% at home and the only exception will be birthday parties & holidays. I find that if my kids and I stay off G/D 95% of the time, our symptoms retreat to a tolerable level.
I am sure for others with Celiac, they would rejoice in being able to do the "sometimes" thing. For me it is a difficult compromise I have come to with my kids. I used to insist on staying GF/DF even at parties. It was VERY difficult. My kids were to the point of not wanting to attend parties rather than stay GF/DF at them. I am not sure I am sending the right message when I allow it "for special occasions" as if gluten is a treat they are being denied. I hope as they grow and mature, they will choose to stay off G/D on their own. My son is now able to identify the symptoms he suffers as a result of eating the offending food but is not always able to make the choice he knows is best for his health.
My goal is to control our home environment and keep us away from fast food for the moment. I am going back to stocking up on the many, many great GF/DF foods that are out there.
