Gordon Brown's wife Sarah has written an essay on the "debilitating pain" of losing the couple's baby daughter Jennifer.
The 47-year-old - who has had two children since - wrote: " The cliché that the passage of time helps is certainly true."
"The first lesson is to recognise that the big overwhelming, debilitating pain that hits from time to time does subside.... and you learn that you do come out of the other side each time."
"There is a temptation to put something that hurts to one side in order to cope better in daily life. Actually the reverse is true."
She added: " Just recognising the full extent of your love means you can cherish, remember and properly honour the person you have lost.
"I learned simply that I did not need a way to mend myself, nor to return to being the person I was before."
Jennifer - Sarah's first child - died in 2002 after suffering from a brain haemorrhage. She had been born two months premature and lived for just over a week.
Sarah's words form part of a book of essays entitled The Death of a Child.
Proceeds from the book's sale will go to the Child Bereavement Charity.
