I’m the children’s ministry director at our church, and it sounds like you need to talk to your CM director or nursery coordinator. In the case of kids with special needs, we actually work as a team with our parents to make sure our kids’ needs are being met – both physical and spiritual. The food allergies definitely need to be addressed – his health depends on it! Schedule a meeting and make sure you bring something in writing about what needs to be done (or not be done). My son has a life-threatening peanut allergy, and I have signs posted all over our classrooms. I also bring his Epi Pen to church every week, just in case something unexpected happens. And, yes, unfortunately, you’ll have to give everyone instructions EVERY WEEK. It’s frustrating, but it’s definitely worth the time and effort. My ASD son has milk, wheat, and egg allergies, and I’m constantly reminding people not to feed him anything that I don’t send for him to eat. Praying that things work out for you!
