Lonie has some fantastic ideas. As for baby food, I'd recommend making your own baby food over store brought.....
Naseau is probably a side effect from her pain killers. I am surprised they even gave her pain killers. With dementia it tends to work the opposite way on people. She probably is in more pain than you think. My grandmother, I took care of her til recently, she has dementia. After her surgery she was given ibprofen for the pain. In my honest opinion, I'd get a new doctor for her and one who actually specializes with Dementia patients. She could be over medicated too. She needs to go see a doctor hon, preferbably whom specializes in dementia.
I worked in a kitchen in a nursing facility before I went to CNA for 3 years. An easy way of making thicknesses is adding a tiny bit of liquid at a time. For example: pudding puree (baby food really thick) cookie put the cookie in a blender and add a tablespoon of milk or water. Mix.. add liquid til you get "pudding". If needed thinner like mechnical soft foods.. its basically shredding all the food with a tiny bit of moisture to make it like a cooked speghetti noodle when u cut it..soft.
We gave grandma 3 ensures a day. After awhile, she thought it was "too sweet" so I poured ensure into a glass half way, and then the other half with milk and stirred it. She just loved the "chocolate" milk she kept getting.
Also til you can get in with the doctor, try even smaller portions Ie: breakfast: 1/2 banana snack: 1 piece of toast, lightly buttered lunch: 4oz chicken noodle soup snack: 3 cooked baby carrots supper: 1/2 sandwhich, 1 cup of broth snack: small smoothie (smoothie consists of fruit, veggies, icecream and ensure/ or milk) (I usually did the other half of banana, icecream, cooked or canned veggie of 1/2 serving so it blends better, icecream, ensure, and i added extra fruit to make it taste real good and so grandma didnt taste veggies). I used ensure, but that was to give Grandma extra vitamins) Doing it small like this, offers her a semi balanced diet. The ensure provides vitamins and minerals. In fact, I drink ensure because I am in chemotherapy and find eating difficult on lots of days.
I found it easier for grandma to drink fluids than to eat, although I managed to get her to eat small meals. I would make sure the food was mechnical soft ie: pasta with alfredo sauce, etc and some cooked really soft veggies sometimes i did brocoli, peas, carrots, whatever I had. But if she wouldn't eat for me, I'd go mix half milk half ensure because even ensure has protein and carbs and have her drink that.
Another thing, my grandma has a weakness for hamburgers. Seriously, she gets excited when we ask her if she wants to go to McDonalds. She will eat a hamburger and a few fries every time.
