Help my son Riley walk again

Thursday night my 18 month old son walked up stairs to bed. Friday morning we brought him back down stairs and he wasn't able to walk anymore. Come Sunday he wasn't even able to sit up. He caught a very rare virus that attacked his body. Called the Entrovirus D68 Now we don't know if he will ever walk again. I am not a religious person but not ashamed to say I have prayed everyday since that he will walk again. This happened a few weeks ago now and we have been told he needs intensive physio therapy. I am raising money to help pay for at much treatment as possible and get give him the best chance possible of walking again
