When devoted mum Lucy Worthington knew she was going to die after an eight-year battle with cancer, she wanted to make sure her husband Mark would know exactly how to bring up their four girls.
Lucy, who was 41, was in the process of writing a detailed instruction manual with tips on everything from styling their daughters' hair to helping them through puberty, before she was cruelly taken from her family on November 6.
But now Lucy's 13-year-old daughter Emily has vowed to finish her mum's booklet.
Lucy started writing the guide to ensure Mark, 45, would be able to cope as a single dad to Emily, Katie, 10, and twins Keziah and Lillia, both eight.
Mark, from Derby, explained: "Lucy got so weak that she wasn't able to finish the book but she chatted about what she wanted to write and Emily knows so many different little things that she used to do.
"She wanted to make memory boxes for each of the girls too and got them started, but now it is up to us to fill them with more memories.
"She wrote letters to the girls too asking them not to be angry that she had died but to understand that she was in a better place now.
"Emily has so many traits of her mum and can handle the three younger girls when they're fighting or when they're upset."
Emily wants to make sure that her younger sisters never forget all that their mother did. She now helps her father style their hair in the morning and reminds him of all the little things that Lucy used to do such as marking birthdays on calendars and helping organise things for school.
As well as tips on how to deal with obstacles in life there were also strict instructions on her funeral arrangements and what jewellery to give to each of the girls.
Mark said: "When she knew her life was almost over, Lucy turned to me and said 'make sure the girls know that I fought to be with them for as long as I could.
"My wife lived for the girls. Every new treatment the doctors could find she would try, just to have as long and full a life as she could have with them.
"That was the sort of woman she was, selfless, caring and the sort of woman who always put other
Emily said: "I miss my mum a lot but I know that dad and the other girls need me too.
"Dad doesn't know how to plait hair or do anything girly so we have to teach him, if that means that he has to have his nails painted then that is something he just has to face.
"I need to make sure that he picks nice clothes for us all as mum always wanted us to look our best, but as long as he takes us shopping with him I'm sure he can pick some nice things.
"I remember all the little things that mum used to do, just things that made her a little special, and I want to make sure that the girls learn all of those too and never forget the things mum did for us.
"Christmas is going to be strange without her because we had so many different things that she used to do and not having her here is going to feel odd.
"I was angry at first that she had gone but now I understand that it was better for her to not be in pain."
Lucy was diagnosed with breast cancer after finding a lump three weeks after she gave birth to her twin daughters. She had a mastectomy but was unable to join in with many family activities, such as swimming.
For the next five years the couple attended regular check-ups hoping that Lucy was successful in her battle but after complaining of pains in her chest scans found she had bone cancer.
Mark said: "We were devastated that it had returned. We didn't hide it from the girls but we were careful about what we said to them.
"Having to tell them 'mummy has cancer again' was heartbreaking. By then Emily was older and understood a bit more and simply asked 'can you die from cancer?'
"This broke our hearts as we just didn't know what to tell her."
In her final few days Lucy was taken to hospital and handed Mark the guide that outlined what he would need to do.
While the book was not finished she also managed to write letters to her daughters asking them not to be angry or hurt that she had died.
Mark said: "Life will never be the same without her but I have four incredible girls that I have to live for, I promised Lucy that I would do that for her."
