We were told to start introducing dairy in small quantities, like bought products that contain butter, etc, then to try a bit of butter on bread or similar, then a bit of cheese, then yoghurt ... but I decided to go straight for yoghurt and he was fine!! Still not tried plain\heated milk.
Basically just introduce the less raw dairy food first a bit at a time and see if there is a reaction.
