What to Expect, the world’s best known, most trusted pregnancy and parenting brand, offers a pregnancy and baby app that helps you prepare for parenthood and guides you through your journey day-by-day and week-by-week. 

The What to Expect pregnancy and parenting app — produced by our team of award-winning journalists, writers, editors, physicians and other pregnancy and parenting health experts, including the brand's founder Heidi Murkoff herself — guides you through every phase of your parenting journey, from starting a family to pregnancy and the first years of your child's life, when he or she is a baby through the toddler phase.

Based on your due date or baby’s birthday, you’ll receive personalized info about your baby’s development, as well as expert articles, tips, helpful tools, compelling videos and more. 

Once you enter your due date and start using our pregnancy app, you can join a tight-knit community of parents and parents-to-be and get plenty of support from our active, caring birth-month groups. 

You’ll get brand new tools and support every step of the way — which can help you have a happy, healthy pregnancy. Once baby is born, you'll get answers, advice and guidance as you navigate life as a new parent. When your baby arrives, you’ll get regular updates on his or her development and growth, as well as expert advice on everything from postpartum healing and feeding to sleep schedules and milestones.
