@bentossell great questions. Oogababy is a Norway-based startup which aims to simplify parents' lives. Our first step towards this goal was the launch of the Oogababy app back in 2013. Since then our users have shown us what to do and not to do. Based on the feedback we received and the lessons we learned, we are now on a mission to introduce distinct and simple products with room for future advancements. Oogababy Health is the first result of our new product mission. We built Oogababy Health to help parents understand their children's development and its features are based on features that were already introduced in the Oogababy app. With a simple design and clear focus, the app makes it easier for us to continue down the road of developing health-related features. Many parents attempt to track development of their children through visual comparison to other children. However, tracking growth and development is a much more complex science. While most babies develop skills in a particular order, there can be a wide age difference for when milestones are acheived. Most babies learn to crawl before they walk. However, the age at which babies learn to crawl or walk varies significantly amongst babies. Parents often treat development as a race but fail to understand babies' individual differences. With Oogababy Health, parents can stay informed and plan ahead based on realistic expectations of their children’s development. With a few taps parents can find out if their child is developing in accordance with the World Health Organization (WHO) standards. So back to your questions. Our predictions of milestones (in particular, the six gross motor milestones) are based on the WHO Motor Development Study: Windows of achievement for six gross motor development milestones (http://www.who.int/childgrowth/s...). The study states that "The data generated by our design were analysed using appropriate statistical methods and employed failure time models that fitted the data appropriately." Based on this we believe that our predictions of milestones are scientifically accurate. As to whether or not there is a need for panic or to seek medical advice if a milestone is not acheived within the predicted timespan, parents will need to determine the individual circumstances related to their case. As mentioned above we try to give parents realistic expectations of their children’s development and note that most babies (not all babies) develop skills in a particular order.

@mychristinahall glad that you like Oogababy Health.

Please feel free to give additional feedback.

@mikaellowgren glad that you like Oogababy Health. We are planning a number of new features and adding more milestones is absolutely in our plans. Thank you for your suggestion! I will add "first tooth" to the list :)
