My mother in law is very hard of hearing. Has come on over the last 5 years. Had her tested and she 'gets' 2 words out of ten spoken in her left ear and 3-4 in her right ear. She tried a hearing aid, but amplification just isn't the problem. She has nerve deafness and only a cochlear implant will help. She is 91 with many serious health issues - so surgery is out of the question.
Question: WHY won't she LOOK AT ME when I speak to her so that she can at least understand (by lip reading) some of what I say. She will act like she has hear what I say and then if I ask her to tell me what I just said she will say she didn't understand. This is just a TINY daily irritation but I wish I knew WHY she is doing this. As they say, YA GOTTA JUST ''LET IT GO.................''
Given the extent of her hearing deficit, it might be that she does only hear a small portion of what's being said.
You mentioned lip reading - has she actually been trained in how to do it? If not, she probably can't.
Make certain that your FIL does not have dementia or something that could interfere with his ability to sense when or if he is hungry. Otherwise, just make a NEW ROUTINE where you make breakfast once for the family (leave his on the counter for him when he is ready for it) and tell him where the frozen meals are kept and make sure there is always something handy for him.
As long as he is 'able' to nuke food when he is hungry and recognize hunger - he will eventually eat. As they grow older they do eat less often. My MIL likes to snack. I keep string cheese, nuts and protein bars (make sure they are truly protein bars and not just the junk kind) and fruit that she can eat whenever she feels like it. Keep these things near his chair. Hope these suggestions help. Hang in there!!
