Dawn Taylor lives near Ruthin in Denbighshire with her partner and nine-year-old son.
She works two hours per day at the local primary school, and her partner is a painter and decorator.
She told ITV News: "It's a struggle every single day. For Christmas I've asked family and friends: 'Just get my son clothes'. I can't afford to go shopping and buy him clothes."
She added: "We're too honest to say: 'Forget working - we'll go on benefits'. We want to work. But we're struggling."
