What does Cribsheet say about breastfeeding?

The book reviews sleep-training studies, noting modest benefits and no long-term harm. Oster encourages parents to weigh sleep-deprivation costs against their comfort with methods like cry-it-out, emphasizing there’s no universally “correct” approach.

What controversial topics does Cribsheet address?

Oster tackles polarized issues like vaccine safety, daycare vs. nannies, and screen time. She critiques weak studies behind common warnings (e.g., “screen time causes ADHD”) and provides frameworks to assess risks based on family context.

What unique framework does Cribsheet provide?

Oster introduces decision matrices to quantify trade-offs (e.g., breastfeeding’s health benefits vs. maternal time costs). This tool helps parents align choices with their priorities and constraints.
