Good to hear back from you Flake - and glad the support has kicked in.
I'll just say again - take this opportunity to tell everyone who comes into contact with your mum EXACTLY what her situation is and all your concerns so that everything is noted and logged.
Dad too took a while to settle back to eating - Amy in the US and Long-Suffering have given good hints to help. I gave dad Complan etc from the chemist, hot and cold, he actually liked those, and his favourite chocolate biscuits, also jellies - with more and more fruit in - and custard or ice cream, and trifle, rice pudding, those powdered deserts you make up with milk; lots of those easy to swallow foods and sweet seemed to be preferred for a while. Then mashed banana sandwich, soups, and mashed veg .... And I didn't offer too much at once so he felt he could manage a portion. Little and offered often seemed to go down best, with no pressure to eat so he wasn't anxious.
And definitely agree with Amy's mirror eating, he seemed to have lost confidence in what to do, how to eat.
This pattern worked well for mum, too I asked for Complan via the surgery and have now got it on prescription ....every little helps!
I like Amy's description of mirror eating. The only trouble is, I'm trying to lose weight for my daughter's wedding.....sweet things are the last thing I need.....however, it really does seem to help mum if I eat with her in this way, so no option, really xx
