After a break and then doing some spot research again, I am able to confirm some of my thoughts on the state of health in this family and what to do about it.
The "what to do about it" is still extreme, but question is, can we really be without considering the drawbacks I see in untreated illness?
Sooo looking forward to the medical visit next week (and the family gathering on Easter a couple of weeks from now).
For myself, I am starting to prepare to go on the "GAPS diet". I am not dragging the rest of the family into this before I have seen some results in myself...
