Best thing you can do for them! First-degree family members (parents, siblings, children), who have the same genotype as the family member with celiac disease, have up to a 40% risk of developing celiac disease. Make sure you and they get enough vitamin D and iodine in their diet.   Iodine deficiency is a significant cause of mental developmental problems in children, including implications on reproductive functions and lowering of IQ levels in school-aged children. Vitamin D deficiency is common in the United States, affecting up to 42% of the population.

Thanks. I ve joined coeliac uk but found them particularly unhelpful - they told me to eat gluten for 6 weeks then have an  endoscopy! I m actually a retired hospital dietician so pretty well know what I m doing…… Louise 

You are very welcome.😊  Do keep posting if we can help any further, and also if you aren't a member already I would recommend joining Coeliac UK if only for one year - they produce a very good gluten-free food and drink guide, a printed copy and also an app you can use on a smartphone which I am told is very helpful when one shops. I think the one thing I would say is be extra vigilant when eating out.  Never feel afraid to question the service staff.  I think most of my glutenings have happened away from the home.

Thank you everyone for your super responses. Louise 

Thank you! I’m currently the breadwinner as my husband is pursuing a finance degree so the nights that I am at work they can eat whatever my husband makes but when I am home we have gluten free meals and no complaints so far! I definitely don’t have a choice but to switch but I think slowly transitioning my family is good!😀
