What to give nursing staff?

Hi everyone - Were looking for ideas. My 91-year-old mother lives in assisted care and the staff are absolutely wonderful to her. Each year we try to get something for the nursing staff. We know there are about 6 or 7 nurses and aides on the morning and afternoon shift, and we know several of them who have been helping her over the years and really give her individual attention. There's also an overnight and weekend shift that we don't usually see.

Now we'd like to show our appreciate with a holiday gift for them. We've given chocolates and cookies in previous years, and had them delivered for different shifts, but we know they get lots of these goodies at this time of year and wondered if there was something that would be more appreciated. We'd especially love to hear ideas from anyone who works in a nursing team and could let us know what you'd really like to receive as a staff. Among the three of us, we can probably afford about $150-$175 for the total gift.

Thanks!
