I'm not sure if this is the best place to post or not, as DDs problems are intolerance rather than allergy, not life threatening etc, but can make her pretty ill, very ill if she ingests a lot of the wrong uncooked cheese, drinks cold milk etc etc, so I'm hoping someone here might have some advice :)
My DD has an IBS diagnosis & Urticaria, her triggers been artificial food additive & lactose, we've been managing it mostly fine for years & I cook from scratch, so she generally doesn't miss out, but we are now hitting the age of over night School trips etc & realising, especially with the lactose intolerance just how ignorant a lot of people are on the subject - understandable if you don't have to deal with it, but I do sometimes wish DCs meals providers etc were a bit more enlightened 
Anyway, I remember reading somewhere about milk sugar enzyme supplements, I think its called lactase, or something similar
- I'm wondering if anyone knows...
exactly what they are,
what is a good brand
& are these okay for kids?
I'm thinking these might be a good idea to take on the run up to & during an upcoming School trip, in the hope of making things easier to manage whilst she's away from home & she's not restricted by the overly cautious diary free diets that seem to be the norm when ever this comes up :(
