probiotics did no difference for our kids. But our younger DS3.10, the one who has a formal autism diagnosis (though we're still debating it) is extremely sensitive to dairy and has to be on a 100% casein / dairy free diet. He's now finally starting to talk and communicate but every couple weeks we try little bit of dairy just to see if we're not keeping him on a strict diet for no good reason and just a bit of dairy stops him completely from talking (not a single word from him), he starts screaming, gets aggressive, and it takes a good week for him to get back to normal. BUT I am not convinced it's an Autism diet (both boys are on both Gluten and Casein free diet). I wonder if the kids who react so well to these diets might have other developmental issues and diagnoses that may be misdiagnosed as autism? Both boys have food and environmental allergies so they are prone to being sensitive to all kinds of things.
