Hi Elaine, I was wondering if this resident in question lived alone prior to residential care. If so, my thought is maybe they only had breakfast as many elderly living alone eat like sparrows. I know before I moved mum and dad nearer to me she only ate a bowl of albran sprinkled with muesli for breakfast and a cup of yogurt at night, it became a learnt habit and one that was very hard to change. Love your caring ways. Taffy.
