I actually like the gluten free foods, since I have eaten this way with my granddaughter who also is not Celiac, but she is sensitive to gluten and has been since birth.
We did not figure it out right away but every time her dad took her for the evening, she would come home screaming. It turned out he was giving her crackers so that she would not be ready to nurse when her mom got her back for breast feeding. Instead it was giving her stomach pain which, even though she was hungry, she could not eat.
I had to quit sharing with her as the labelling changed to warn of nut contamination issues with the flour. Oh, my granddaughter also could only have rice flour and products every other day, so we could not depend on rice.
