We went on a short vacation. Dad was okay. Sister would come in and check on him and stay for hours. While we were gone, he got a bladder infection. She said he worried all the time we were gone about us. And got very little sleep. and got confused. Now back he seems to be a little better. but still stumbles on his sentences sometimes although he read me a short story perfectly earlier. He seems unable sometimes to get the words out. He still has more antibiotics to take. He wasn't like this before. Talked perfectly, never stuttered and it is painful to see him try and get the words out when he has trouble. Also wondering if since his routine changed when we left if that has something to do with it. Someone asked about a stroke and I cannot see any signs of that. He has been sleeping a little better also. since we got back. My hopes are that is that he hasn't had enough sleep, very little while we were gone about 5 days. His normal routine would be to lay down quite a few times during the day and sister said he wouldn't lay down..also he stayed up till midnight which he has never done before.
