Yes, stress is a biggie and I understand well how having two grandchildren with cp (or any other problem) is stressful. Problems affect the entire family, not just the one with the diagnosis.
TAKE YOUR TIME, so that you can stay focused. There is no pressure here: go through things at your own pace, use the site as you want! But... use it. You'll see me write it repeatedly: do the Diet Stages, preferably with care. They can make a huge difference and even help you maintain self-motivation!
Looking forward to getting to know you,
