because my mom is on medicaid, the nursing home can't charge her for diapers, shampoo or toothpaste.

In addition to nursing care, some of the items included in the Medicaid nursing home payment are a toothbrush, toothpaste, shaving cream, razor, soap, shampoo, linens, a comb and brush, bandages and continence supplies. If Medicaid is paying for your mother’s nursing home care, you may choose to bring some of these items, but the nursing home may not require you to do so, or charge your mother or you more if you do not.
