We think there is a great opportunity to learn about efficacy in child development and parenting practices here, and are very excited by the potential that brings!
My first reaction is that our goal is to support parents and we'd want to be very careful before doing anything with their data. BUT if we can support the field at the same time as being 100% transparent with our families it would be great (e.g. they'd have to explicitly opt-in.)
But again, a great problem for the future :)
