We identified that Dd is dairy intolerant, can’t seem to find out whether cooked or uncooked dairy makes a difference and quite happy to exclude all dairy. She is 6 and has been dairy free for 2yrs. Three weeks ago she was contaminated with food that had milk in and has had leaky gut ever since, soiled knickers during the day and seapage at night in a nappy. We haven’t had many solid poos since the contamination. What can I do? Has her gut been damaged as a result of the dairy and how can I help get her back on track?
