I'm following everything in the app but my daughter was born 6 weeks before her Estimated delivery date. Should I be using her birthday or her EDD?

Hi, thank you for your question! Dr Frans says that you should use the EDD, as development starts at conception, and not at birth :) Whether you are giving birth early or late, does not speed up or slow down your baby's brain development.
