This study includes up to nine timepoints: Some occur during pregnancy; one is shortly after delivery; and several occur during your child’s early years. Some visits are in person, and some are remote. In addition to taking high-resolution magnetic resonance images, we will study your blood samples and cheek swabs to better understand factors that impact placental development. And we’ll track your baby’s neurodevelopment through age 4.

To thank you for the value of your time, you may receive up to a total of $550 for participating in this study. Payments will be made after each completed study activity via a reloadable debit card. You also will receive up to $15 for transportation or a parking voucher and up to $15 for meals for each in-person, study-related visit.
