New w/a question: What about other peoples houses?

[Guest guest]

We haven't started the diet yet since I am still waiting for the book

so I can figure out what to do. We often spend time at my IL's house

and sometimes my ds stays there w/o us. Should we send his own food

w/him? I'll give them a list of what he can/can't eat(which they're

kind of used to since he isn't supposed to have dairy), but is there

anything I can/should do?

TIA,

Janice
