My girl was allergic to bananas too, she started using homeopathic medicine, finally she can eat bananas and many other food that she couldn't eat before.
He can't even be around banana's he gets bloody noses from them. I will look into homopathic but he also has Celiac disease so gluten can never be added back in.
What a cute guy! Looks like he is having so much fun.
Regarding the homeopathics - I notice that you indicated that your son's got a dairy allergy. Homeopathics often contain lactose in them which could potentially cause a reaction for someone with a milk allergy. Be careful.
