Economist Emily Oster applies data to pregnancy and parenting decisions

Substack Parenting Weekly Updated Oct 2026

About

ParentData comes from Emily Oster, the Brown University economist who built a readership well before she started a newsletter, through books like "Expecting Better" and "Cribsheet" that applied actual data to pregnancy and early parenting. The newsletter keeps that same project going week to week: she picks a question parents are anxious about, pulls the underlying studies, and walks through what they really show versus what headlines claimed.

The tone is calm and a little dry, more statistics seminar than parenting blog, which is exactly the appeal for readers tired of absolute rules. Expect pieces on sleep training, screen time, or RSV vaccines, usually landing on "here's the actual risk, here's what I'd do" rather than a verdict dressed up as consensus.
