It seems like most of us get more sensitive to being exposed to gluten the longer we go without it. I can say that for me, now when I get bloating/constipation pain like I used to, I'm shocked that I could deal with it so well for 30 years. You do get used to constant pain; and once you go without it, it is hard to get it again. But it does help keep us on track.
I hardly ever get pains now from gluten or other dietary factors, so you can be assured that if you get this thing handled, her life is going to be so much better. Good for you for figuring it out and making that effort.
Thank you for you for your responses! I am so grateful that we have discovered her celiac so early in her life. It's good to know that *she* will know when she has been glutened and the reliance won't be so much on us and she can become more independent as she grows older.
