All of this is great news. I was happy to hear your mom was able to see him in the room. Like your dad, my dad had a heart attack during covid and we could not get to see him. It was very problematic as they thought he understood everything they were telling him. He is now walking 1/2 mile a day with one of us with him. Your dad will get stronger each day and just keep moving forward with him as fast as he wants to go. Very Happy to hear all this good news!!
