Peaches Geldof wrote about her life of "bliss" in her final parenting column - published posthumously - before her death.
The 25-year-old mother of two had recently signed up as a columnist for Mother & Baby magazine.
The words, in which she credits her young sons Astala and Phaedra with rescuing her from a life of "wanton wanderlust", have been published following her sudden death "as a tribute to Peaches and with the blessing of her family".
Peaches penned the column some time before her 25th birthday in March, writing: " I wanted an anchor - I craved it.
"And, when I had two wailing, smiling, joyful little blobs of waddling pink flesh, they became my entire existence, and saved me from one of pure apathy."
The former party girl wrote that she found herself suddenly "friendless" and felt "alienated" as "fair-weather" friends didn't want to know once she couldn't go out for "wine-soaked" dinners.
But she soon realised that "everything else was nothingness and it just... didn't matter. I had the perfect life - two beautiful babies who loved me more than anything. It was, and is, bliss."
"Now, with a new-found group of mummy mates, both locally and online... I'm happier than ever," she said.
"My real old friends have stuck by me and connect me to my old life (I sometimes forget I'm only 24), treating me to nights out that let me forget about dirty nappies at least for a minute.
"So, I've achieved a sort of perfect balance."
Peaches, whose TV presenter mum Paula Yates died in 2000 of a drug overdose, added: "Right now life is good. And being a mum is the best part of it."
Peaches Geldof's grieving family may find out what caused her sudden death when a post-mortem examination takes place today.
The body of mother-of-two Ms Geldof, 25, was found at her home in Wrotham, Kent, on Monday and police have said her death is not considered suspicious but was unexplained.
Her father Bob released a touching tribute in which he said the family was suffering "beyond pain" and her elder sister Fifi Trixibelle Geldof yesterday posted a picture on Instagram of the two of them together when they were children and wrote: ''My beautiful baby sister.... Gone but never forgotten. I love you Peaches x.''
Ms Geldof was just 11 when her mother, TV presenter Paula Yates, died from an accidental heroin overdose in 2000, aged 41.
Ms Geldof, who had two young sons with her second husband, musician Tom Cohen, was a prolific tweeter and the final message she sent on Sunday was a picture of herself as a child with her mother, with the message "me and my mum".
Her body was found on Monday afternoon after officers were called "following a report of concern for the welfare of a woman", a Kent Police spokesman said.
The police spokesman said: "Officers were called to the 25-year-old's home in Fairseat Lane, Wrotham at 1.35pm on Monday April 7 2014. Peaches was pronounced dead at the scene.
"The death is being treated as a non-suspicious, but an unexplained sudden death.
"Officers are working to establish the circumstances and will be compiling a report of their findings for the coroner."
A Kent County Council spokesman said yesterday that Ms Geldof's body has been transferred to Darent Valley Hospital, Dartford, where the post-mortem examination will take place.
A coroner will open an investigation after the results of the initial post-mortem examination have been received.
A decision on whether to hold an inquest will be made depending on the final results of the post-mortem, which could take several weeks.
Ms Geldof's family led the tributes which flooded in after her death was announced.
"She was the wildest, funniest, cleverest, wittiest and the most bonkers of all of us," her father's statement said.
"Writing 'was' destroys me afresh. What a beautiful child. How is this possible that we will not see her again? How is that bearable?
"We loved her and will cherish her forever. How sad that sentence is.
"Tom and her sons Astala and Phaedra will always belong in our family, fractured so often, but never broken."
The statement was signed by Bob Geldof, his partner Jeanne Marine, and Peaches' sisters Fifi, Pixie and Tiger.
Chen said: "My beloved wife Peaches was adored by myself and her two sons Astala and Phaedra and I shall bring them up with their mother in their hearts every day. We shall love her for ever."
Ms Geldof's oldest son Astala is 23 months old, while 11-month-old Phaedra was born on what would have been her mother's 54th birthday.
Her parents divorced in 1996 after Yates began a relationship with INXS frontman Michael Hutchence.
Hutchence was found dead in a hotel room in Sydney, Australia, in 1997, and Yates went on to lose custody of the three daughters she had with Geldof - Peaches, Pixie and Fifi - the following year.
Geldof later adopted Yates and Hutchence's daughter Heavenly Hiraani Tiger Lily.
Ms Geldof was 19 when she married US musician Max Drummey at the Little White Wedding Chapel in Las Vegas in August 2008. The couple announced that they had decided to split amicably in February 2009 before divorcing in 2011.
Ms Geldof married Cohen, lead singer of south-east London band SCUM, in September 2012 at the church in Davington, Kent, where her parents married 26 years earlier. It was also where her mother's funeral was held.
A host of celebrities including Phillip Schofield, Holly Willoughby, Ellie Goulding, Simon Cowell and Lily Allen paid tribute.
Model Daisy Lowe posted a picture of a broken heart on Twitter.
