Hello jimjams, so sorry to call on you for advice when you have so much on your plate. For you or anyone else who might know, 20 month old ds managed to eat a whole cow's milk yoghurt whilst at a friend's today. he has never eaten dairy before because of his gut inflammation in the past and the advice to keep him off dairy and gluten to avoid development problems. Is one yoghurt likely to cause problems developmentally? And is it reversible if we stay on the dairy free gluten free diet? Bit annoyed and rather worried now - he's been doing so brilliantly recently. any advice gratefully received.
