Caroline Fertleman, MD, is the consultant pediatrician at Whittington Hospital in London. Simone Cave is the health editor at the DailyMirror. They each live with their families in London.

Library Journal, starred review, 2/17/11 "In June 2009, I gave a starred review to Fertleman and Cave's Potty Training Boys the Easy Way. This version for girls is just as excellent. Physician Fertleman (writing with health editor Cave) knows just how to present the relevant information to parents, covering topics like early preparation, night training, and common medical problems. Among the plethora of books on potty training (which include some idiotic titles that endorse 'naturally training' six-month-olds), Fertleman's two offerings should be the go-to titles for all things poop and pee. Unequivocally recommended." Mid-Ohio Valley Parent Magazine, March 2011 "This is a great resource for parents trying to tackle the potty training issue!"
