Question 1 of 9

Why does the author argue that an economist's framework is highly applicable to parenting?

A. Economists have access to better pediatric data than doctors.
B. Parenting, like economics, fundamentally revolves around making difficult decisions based on costs, benefits, and personal circumstances.
C. Economics focuses strictly on the financial costs of raising a child, which is the most important factor.
D. Economists are trained to remove all emotion from family dynamics.

Question 2 of 9

According to the economic approach to parenting, how should a parent find the single 'right' answer to questions like whether to breastfeed or use daycare?

A. By exclusively following the advice of pediatricians.
B. By choosing the option with the lowest financial cost.
C. There is no single 'right' answer, as the correct choice depends entirely on a family's unique preferences and circumstances.
D. By looking at which choice has the most peer-reviewed studies supporting it.

Question 3 of 9

When deciding whether to return to work or stay home with a child, a parent must weigh the financial gain against the loss of time spent with the child. Which two economic concepts best describe this trade-off?

A. Supply and demand
B. Sunk cost and comparative advantage
C. Opportunity cost and marginal value
D. Inflation and depreciation

Question 4 of 9

What does the comparison between the risks of co-sleeping and driving with a baby illustrate about parental decision-making?

A. Driving is statistically much safer than co-sleeping.
B. Co-sleeping provides no actual benefits to offset its high risks.
C. Parents should avoid both co-sleeping and driving at all costs.
D. Parents often let emotion muddle their assessment of risk, accepting higher everyday risks while panicking over lower ones.

Question 5 of 9

Why does the correlation between breastfeeding and higher child IQ often decrease or disappear in scientific studies?

A. Because researchers adjust for confounding variables like the mother's education and income, which are the actual drivers of the higher IQ.
B. Because formula companies fund most of the research.
C. Because IQ tests are inherently biased against breastfed children.
D. Because the sample sizes of breastfeeding studies are usually too small.

Question 6 of 9

Why are large-scale randomized controlled trials considered the most reliable form of data for parental decision-making?

A. They are the only studies that track children from birth through adulthood.
B. Randomly splitting participants ensures that the only difference between groups is the variable being tested, isolating its true effect.
C. They rely on parents' subjective memories, which are surprisingly accurate.
D. They completely eliminate the need to consider a family's personal preferences.

Question 7 of 9

What is a key characteristic of the most reliable observational studies?

A. They focus exclusively on a small group of 10 to 12 children.
B. They intentionally introduce confounding variables to test a child's resilience.
C. They compare siblings from the same family to naturally control for socioeconomic and familial background variables.
D. They rely on case-control methods to find common symptoms across different demographics.

Question 8 of 9

Why does the author warn parents to be highly skeptical of case-control studies, such as Andrew Wakefield's 1998 vaccine study?

A. They are usually conducted by economists rather than medical professionals.
B. They require large-scale randomization, which is unethical in pediatric research.
C. They focus too much on sibling comparisons, ignoring broader population trends.
D. They often have very small sample sizes and are highly susceptible to unthought-of confounding variables, recall bias, or data manipulation.

Question 9 of 9

What is the author's primary actionable advice for parents worrying about unlikely events, such as a baby getting stung by a bee on vacation?

A. Always carry a comprehensive medical kit to mitigate all possible risks.
B. Try not to think about it, because excessive anxiety over unlikely events will make you too frazzled to make good parenting decisions.
C. Conduct a thorough risk assessment of the vacation destination before leaving.
D. Calculate the exact opportunity cost of the vacation to determine if the risk is worth it.

Cribsheet Summary & Overview

Parenting can feel like moving into a new life overnight—one filled with love, uncertainty, and a constant stream of opinions. This narration reframes the early months and years with a steady, supportive voice: you may not control everything, but you can make choices that fit your own family.

Drawing on Emily Oster’s data-minded approach, these chapters walk through the real decisions parents face—hospital routines, newborn sleep and crying, feeding, toddler milestones, screen time, and childcare or returning to work. The focus isn’t on “one right way,” but on weighing evidence, noticing what works, and letting go of guilt.

Who Should Listen to Cribsheet?

New or expecting parents who feel anxious or flooded by conflicting parenting advice and want a calmer way to decide.
Parents navigating feeding, sleep, childcare, or work decisions and looking for reassurance that thoughtful choices can look different from one family to another.
