"Becoming a new mother can be extremely overwhelming, and it can lead to increased mental stress. Dr. Pensak has done an exceptional job in examining the ins and out of maternal mental health and providing practical and accessible evidence-based knowledge and strategies for new parents. If you’re an expectant or new parent, Rattled is a must-read."

― Eve Rodsky, New York Times best-selling author of Fair Play and national bestseller Find Your Unicorn Space

"Rattled is a must-read for all mothers. Dr. Pensak seamlessly blends science and practical strategies that finally changes the narrative around ‘mommy brain.’ Eloquently capturing the true wonder of the mother’s brain, Dr. Pensak brings much-needed attention and clarity to the physiological and psychological changes that occur over the course of a mother’s development and shares tangible strategies [and] easy-to-use tools to empower mothers through their own evolution (and protect their mental health). Dr. Pensak is funny, raw, and inviting, sharing her own unique journey into the chaotic and beautiful world of motherhood. Thank you, Dr. Pensak for helping us as mothers feel seen during this time of profound transformation, and for giving us the tools to ‘up the ante’ and thrive. Rattled has instantly reached the top of my list of recommendations for all moms I work with. . . . I can’t wait to recommend to my patients, family, and friends."

"In this incredibly supportive and practical resource for new mothers everywhere, Rattled equips women with what to psychologically expect ‘when you are expecting,’ and guides new mothers through the power and peril of matrescense, the developmental stage of motherhood we didn’t know existed or were taught to believe had no possible upsides. Through a blend of rigorous science and personal anecdotes, Dr. Pensak offers compelling new and alternative explanations for our anxieties and perceived inadequacies while artfully connecting us with a concrete and hopeful path forward."

"Nicole Pensak’s Rattled is essential reading for moms and dads and the loved ones and caregivers who support them. It answers so many of the questions my wife and I had about how motherhood changes, influences, and shapes new moms, and it answers them thoughtfully, empathically, and with the authority of science and practical experience. Pensak is the perfect guide on this journey, enriching Rattled with her experiences as an author, researcher, scientist, therapist―and, of course, mom―trained in post-partum therapy, anxiety, and depression. Highly recommended!"
