Leigh Signal has been a sleep scientist for over 20 years. She is presently associate professor and portfolio director, Fatigue Management and Sleep Health, at the Sleep/Wake Research Centre, Massey University, Wellington. Ten years ago, when she was pregnant with her second child and struggling with her own sleep, she began a series of projects looking at the links between perinatal sleep and mothers’ health. One of the projects she co-led was entitled E, Moe Māmā (‘Go to sleep, mother’). Although when translated it sounds like an instruction, the name is meant to convey care, support and encouragement for mothers to be able to sleep well, which is what she hopes this book helps you do.
