She's likely to tire very quickly and worry about anything new - to start with I'd see if you can find some fairly easy (150/200 piece) jigsaws and just work on one for a short while at a time. If that goes well, then expand to going somewhere with nice sights - depends where you live, but I'm thinking parks, sea view, countryside or nice town - tea and a treat - how's her appetite? Would she go along with (initiative is too much to expect just now) planting something for later in the year - it's good to 'start' something.
