I ended up in hospital again so the kids had to finish for me & they didn't do filters or salt & they didn't do it again today as promised and he doesn't look better to me. I just got home and he didn't even greet me. They had told me he was better but I am not seeing it and too weak to do it myself so I am going to put the 2 Tbsp salt in for now and try not to get angry at the younger generation cause I don't get how they excuse not helping.
