My Mom went into an assisted living center about 6 weeks ago. She has a problem with keeping her food down. Since she had moved in, Mom has lost 8 pounds and now weighs 84lbs. She is 92. I tell her to relax and eat slowly. She says she doesn’t like the food and she can’t help that it comes up. I bought her some Boost. Can she survive on 2 of those a day?
