Initial diagnosis is difficult and the first few months may be stressful but it DOES get easier! Focus on the foods you CAN eat, and indulge in those for now while you get the rest of the menu figured out. Upon my own allergy diagnosis, I ate homemade chocolate pie for two days because it was a comfort food and I knew it was safe! Salads, stir fries, and other simple foods are good places to start. Beware of soups, as some stocks contain gluten, but after that, soup is a pretty good option too. Cooking from scratch takes time but it can help build the confidence of knowing what is in your food, as gluten and dairy creep up everywhere in processed foods, spices, sauces, etc.
I don't have kids but work with them daily. Kids are incredible and will amaze you with their compassion and creative ideas. Let them know that some foods will make you sick and have them create meals that work for everyone. You may be making Namaste pancake mix with fun toppings for a few nights in a row, but the kids may have some really wonderful ideas.

Take a deep breath and keep moving forward.
