Let me start by saying that our idea speaks to three personas from your list: the under-resourced mom, the healthcare provider (Melania), and the support team (Andrea). As to the under-resourced mom, the postpartum registry will allow her to reach out for help that she needs and specifically asks for (she will be able to specify her needs for help/support within the app and reach out to her friends), as well as provide her with the support she lacks and will eliminate her isolation in the interim. We aim to help a mom-to-be by enabling her to plan her journey for a postpartum period in advance, preventing isolation and complications such as PPD. With this postpartum registry, the new mom will be able to ask for postpartum services offered and paid for by friends or maternal professionals. For the healthcare professionals/maternal professionals, their services will be suggestively presented to the mom-to-be so she is aware of their existence in the first place and can get those services as gifts from friends via the registry. Our research shows that many moms are not aware of such services as postpartum doulas, lactation consultants, overnight nurses, etc. and with our app, we will be able to educate the moms about them. As to the support team, they will have a great touchpoint with the new mom to address her needs "articulated" via the postpartum registry app. Friends can gift their time or pay for the services that the mom needs, including the help of maternal specialists. It does take a village!
In regards to your second question, yes, we have done an extensive research among local moms and maternal advocates to find out their pain points and needs. We were first driven by the question: can the postpartum depression be prevented? Here is the needs/pain points diagram that resulted from our research: https://ntsydesign.files.wordpress.com/2017/05/ppda_conceptmapping.png
In addition, to learn more please check out our blog that describes in detail what has been done during the course of development of this idea and how it progressed to its current state - the prototyping phase: https://ntsy.design/blog/
Lastly, based on our research, currently, there is no exact concept like this implemented in the market. We are aiming to increase user adoption by tapping into the familiar idea of a baby registry or wedding registry but extending them beyond material goods adding the ability to provide services or ability to gift time as part of supporting a new life journey.
Please, let me know if there are more questions I can clarify. Sofya
