My nearly 12 year old DS has been put on a renal diet - low phosphate and potassium. I've got the book from the hospital telling me what he can and can't have (very strict to begin with - no swaps or extras for now! 
)
I was wondering if there were any other parents on here in the same position who have been doing it longer and can share some meal ideas or tips? I have a few but I'm feeling a bit lost. Thanks!
