Four-year-old Roxanne Allen's mum Chloe was diagnosed with breast cancer in August 2009 and died last November.
Her dad Mike was diagnosed with a rare form of blood cancer in June 2011 but he is determined to make his last months with his daughter special. He has also set up a trust fund in Roxanne's name to provide for her future.
The 49-year-old baker from Bridgehall, Stockport, said: "I live day-by-day and enjoy every minute I can. I am making plans so that Roxanne is okay and has a stable future.
"Chloe and I have the same attitude, to get on with life and enjoy it. We have never hidden anything from Roxanne.
"She has seen me and her mum at our worst and was at Chloe's bedside when she passed away. She hasn't asked me about my death yet, but she knows I am not well."
The couple married in January 2009, just seven months before Chloe was given the bombshell diagnosis of breast cancer. She was given the all-clear after a mastectomy but then Mike was diagnosed with a rare form of lymphoma, or blood cancer, in June 2011.
The family went on holiday to Disneyland Paris last June for Roxanne's birthday, because they didn't think Mike had long left. When they returned, they found Chloe's cancer had returned - and had spread 'everywhere in her body'.
The last time Mike saw his wife alive he had left her to get his final treatment at The Christie on November 14. She passed away at home while Mike was in hospital.
Mike, who also has a 16-year-old son called Dean, said: "All the signs had been that I would die first. It is shocking to think how quickly she deteriorated.
"I helped Chloe plan her funeral and we both sat down and planned mine."
Mike has arranged for Roxanne to live with his wife's sister, Jane, 51.
The family are in the process of setting up a fundraising account. If you'd like to contribute send an email with the subject 'Roxanne Allen' to email@example.com
