Hello
I know how hard this is, really the doctors are doing their best usually. They do not have the enotional connection with the patient we have, they can not feel that as we can.
Smaller portions of food in smaller dishes seems to help . I am talking tiny dishes, I got condiment bowls , clear ones. Also offer less aromic foods, some foods will smell less served cooler. I know it seems smelling it will trigger interest but it repulses them instead. I served drinks even in small cup with a straw cut in half. Straws seem to make more go down before they realize they drank so much . The carnation drink is great one.
Also try softer foods , blander foods, low colored foods such as tiny soft bread sticks made with a canned dough ( is fine) make them small and place a bit of white cheese on them before baking ( adds calories) teh colored cheese seems to send off " I do not want that" , make them soft and finger small, shakes made with eggs, pulverized fruit, a plop of icecream and a bit of fiber powder, down it goes...after all it is " just a a few sips,please" offered over and over. :) a entire apple with skin, bananna, egg, icecream, and it all went down! ( Blender) you can even hide a scoop of infant formula in it for more health.
TINY bits of raman noodle, crush it before making it, add milk to it to make a broth, I added white cheese to add more portein. Not the healiest of foods but certainly calories!
Make scrambled eggs in muffin tin in oven, stir up egg with a spoon of milk , you can add crumbled bacon bits to this, butter bottom of tins, pour a bit of egg mix in to just cover bottom, bake 350 until done, 5- 8 min they were tiny enough to serve and frige well for later, cut a circle out of lightly taosted bread to serve with it. Best to you. Keep it small.
