Try the milk ladder, it’s what the dr will give you if you’re concerned about a milk allergy. Google it and it should come up with an image. Cut all milk out and then reintroduce using the ladder. We did this and my little girl can have milk fine now in food but has oat milk or soya milk for a drink x
Thank you both ☺️ he actually loved the oat milk last night and have completely cut out dairy now. Hopefully this will help
You’d have to cut all all dairy not just milk to see if it was the issue x
