SJS,
When possible, I try to either make family meals gluten-free or provide a substitute my daughter likes. If I’m preparing meatloaf or similar foods, it’s easy to avoid recipes containing gluten or substitute as necessary. But when I make pizza or cook pasta, I prepare a gluten-free version for my daughter and a regular version for everyone else. Since gluten-free food is much more expensive than regular, this is a lot cheaper than making gluten-free food for everyone, and after trial and error, I’ve found choices she likes. I buy or bake regular and gluten-free cakes, cookies, and other snacks. Generally I try to make sure that if she can’t eat what we have, she finds her choices as attractive as ours, or better.
I usually buy challah for the rest of us from the bakery, and my daughter eats oat matzah.
She’s been gluten-free for most of her life, and doesn’t remember anything else. The diet is sometimes a challenge, but as long as she keeps to it (and b”h the blood tests show that she has) she’ll have no ill effects b”h. And when I think about some of the differential diagnoses I’m grateful for that.
