My DS has never officially been tested for a dairy allergy but back in October, then 7.5 months old, I gave him porridge made with whole milk and yogurt and he had horrible bowel movements and was not himself. I cut out the dairy and everything improved. Fast forward to mid February when he's 11.5 months. I gave him some fromage frais and there were no issues at all. His bowel movements were fine and he was his normal happy self. Since then he's also had some lasagna with ricotta and mozerella with no problems and I thought he'd outgrown his dairy issues. Last night for supper he had fish pie that had a fair bit of whole milk in it and we had a horrid night. He was fine - playing, etc - until it was his bedtime. Then he was up constantly crying, fussing and was just very unsettled. Is there a difference between yogurt/cheese and plain whole milk?
