My 10 month old son has a similar problem to yours. He had a rash on his face the first few times he had dairy (milk, yoghurt) so I avoided it for a while then I tried it again a few times (chocolate spread, cheese) and he had streaming eyes but no rash - not sure why the change. But he does seem to be able to cope with small amounts - butter on toast, croissants, licks of icecream. He hasn't had a reaction for 3 months now so he may be over it. We have an allergy test next week at Kings. My friend's baby had allergies and didn't want to wait for their King's appt so they had a private test done which they said was very good and they got it straight away. So you could do that if you want to find out soon.
