Hi I've just found two allergy cook books I used when I was advised from doc to make ds dairy free. Happyily now he is on a full diet, therefore rather than just sitting in my cupboard they are free to anyone that wants them; as long as post is paid for.
They are:
The child friendly food allergy cookbook (Hammond & Rominger 2004)
The everyday dairy free cookbook (Rogers & White 2006)I can't post them until thursday though as I'm busy during day til then. Let me know if anyone interested, if not it will be freecycle.
