Hi,
We've had this twice with Dad. 18 months ago, when he was in hospital he just stopped eating, and it was really hard to persuade him to try anything. He went down to 7 stone from 12 in the three months he was in hospital, so when he went into a nursing home, I was resigned to it continuing. However, how wrong I was! They fed him thickened milkshakes, with extra cream and ice cream and fruit in. He couldn't get enough of them, and gradually started eating "proper" food again. He got up to 9 stone, and was doing well when he had another big stroke, and then stopped eating again. They tried him with the milkshakes again, but with much less success this time. Then they would put out a plate of pink wafer biscuits on the table where he could reach them. If nobody mentioned them, he would absentmindedly pick them up and eat them! If anyone tried to encourage him, he would just refuse. After a few weeks, he started to eat some of his dinner. I would just start spooning some mashed potato into his mouth and he would eat it. Then if he was given a bowl of pudding he would accept that. This went on throughout August, and this week he has eaten all of his dinner every day. The trick with Dad is just to get him started on something, and it doesn't matter what. Then he seems to remember that he does eat.
I hope it works with your Mum. Dad is also now taking morphine, so it could be that it helps that he is no longer in pain.
Love and hugs,
