Well, first off, it's not just about the foods you make, but some food habits in general - for instance, you want to make sure that you never use a knife on bread and then in mayonnaise or butter or jam afterwards that you will use for him, because it will cross-contaminate. Second, make sure that you read ALL labels, and check for every gluten related ingredient (so, not just flour or wheat gluten, but barley malt, etc.). Also, don't feel like you have to buy "gluten free meals" or foods all the time. You really don't and they can get expensive. I have two sisters and two nieces with celiac and one has been great about adjusting her own recipes, etc. Some easy ideas: eggs, homemade stir fry (check soy sauces though because some brands use barley malt), veggies, cheese, corn tortillas (tacos), meat and potatoes, etc. Just fyi, chicken broth is another thing that sometimes is okay and sometimes not depending, even when it is made by the same brand. All Campbell's soups are out. Rice is great, and there are gluten free flours you can buy to make waffles, etc. Oats are a general no-no because of cross-contamination in the production process. If you want oats, make sure you buy them gluten free. Also, rice noodles are good. You really can stick with a few generally safe things and make a pretty good variety of food. Also, check spices because there are some spices that are not okay (spice mixes, etc.). I know someone else already gave some websites for celiac that have info - I'd also look there. You will probably want to not have him eat out or eat at other people's houses too, at least until you get it down and find some good gluten free menus. There are places that have them. I know that one of my sister's gets sick almost every time she eats away from home, even when she's careful - it's just that lack of control over her diet. Hope that is helpful! Good luck!
