Rutendo Hapaguti, 28, started looking after the victim at her home in Raventhorpe, Peterborough, in January this year as a stand-in for her regular carer.
Hapaguti noted down her card details and during February and last month spent just over £3,400 on flights to Zimbabwe and Zambia, money transfers abroad, a flight and visa for a friend and the holiday to Dubai.
She was arrested on April 1 after the victim's regular carer became suspicious and her grand-daughter contacted police.
Last week (April 19), at Huntingdon Magistrates' Court, Hapaguti, of Priestley Road, Stevenage, pleaded guilty to fraud by false representation and was jailed for 26 weeks.
DC Pippa Burns, who investigated, said: "Hapaguti found herself in a position to take advantage of this vulnerable lady and did so on multiple occasions while the regular carer was on leave.
"It is a gross breach of a position of trust, which is reflected in the prison sentence."
