If she is still playing the Lite version of Virtual Families, none of the items you mention are available. The items that can be purchased in the store are groceries, basic medicines, and career room upgrades. The other items are available only in the full version of the game.

The best strategy for the Lite version is to make sure that there is plenty of food to eat and that obvious ailments are cured as quickly as possible, to avoid further decline in health.
