"[26] Brown chaired the launch of the "new consensus for maternal, newborn and child health" at a 2009 high level event at the United Nations.

At the meeting 10 countries, including Sierra Leone, Ghana and Liberia, declared that they would be dropping medical charges ("user fees") to pregnant women around the time of birth.

The consensus also set out key action steps that research showed could save the lives of more than 10 million women and children by 2015, and that were endorsed by the G8 at their July meeting of that year.

[29][30] The petition aims to hold world leaders to account for the promise of universal primary education made in the Millennium Development Goals (MDG2).

"[86] The Irish Independent describes the book as a "disturbingly giddy, schoolgirlish, exclamation mark-littered diary form" and "nothing in the slightest bit revelatory about it... tiptoeingly discreet", but that "Brown comes across in these pages as a decent and likeable" with "enough gossipy details to satisfy star-hungry readers",[87] with Caitlin Moran declaring: "School run, conference call, Obama for tea – Sarah Brown smiled, and tweeted, through it all.
