Question 1

Why are autism rates increasing? Is there a real epidemic?

Accepted Answer

The rise in autism diagnosis rates is primarily explained by changes in diagnostic criteria, increased awareness, broader screening, and diagnostic substitution — not a true epidemic of new cases. The CDC now reports 1 in 31 children with autism (up from 1 in 150 in 2000), but most researchers at...

Question 2

Should I hold my child back a year before starting kindergarten?

Accepted Answer

The evidence on kindergarten redshirting is mixed and largely does not support it as a universal strategy. Early academic advantages seen in older kindergartners tend to fade by middle school. There is some evidence that younger children in a class are more likely to be diagnosed with ADHD — but ...

Question 3

Are childhood vaccines safe? What does the evidence show?

Accepted Answer

The evidence for childhood vaccine safety is among the most robust in medicine, drawn from clinical trials, post-market surveillance, and studies involving tens of millions of children. No credible scientific evidence links vaccines to autism or other chronic conditions. The original study claimi...

Question 4

What week are you most likely to go into labor?

Accepted Answer

Most babies are not born on their due date. By 38 weeks, only about half of women will have given birth; most first-time mothers without induction will deliver between 39 and 41 weeks. The peak probability of spontaneous labor occurs between weeks 39 and 40, with about 26% of births happening in ...

Question 5

When and how should I start my baby on solid foods?

Accepted Answer

The data supports introducing solid foods around 4–6 months, with the key milestone being readiness signs rather than a rigid age. Early introduction of common allergens — including peanuts, eggs, and dairy — is now recommended based on strong trial evidence, reversing decades of previous guidanc...

Question 6

What foods are actually unsafe during pregnancy?

Accepted Answer

Not all food restrictions in pregnancy carry equal risk. The most important ones are rooted in infection risk: listeria (deli meats, soft cheeses, raw sprouts), toxoplasmosis (raw meat, unwashed produce), and mercury (high-mercury fish like shark, swordfish, and king mackerel). Beyond these, many...

Question 7

How long can breast milk be stored? What are the real rules?

Accepted Answer

CDC guidelines for breast milk storage — 4 hours at room temperature, 4 days in the fridge, 12 months in the freezer — are deliberately conservative. The underlying science shows breast milk has significant antibacterial properties, and minor deviations from these guidelines (leaving milk out for...

Question 8

Are GLP-1 medications like Ozempic safe during pregnancy?

Accepted Answer

Current evidence and medical consensus recommend stopping GLP-1 medications (like Ozempic or Wegovy) before becoming pregnant and not using them during pregnancy. Animal studies suggest possible fetal risk, but human data is extremely limited and the situation is rapidly evolving.

## Evidence Su...

Question 9

Is Tylenol (acetaminophen) safe to take during pregnancy?

Accepted Answer

The best available evidence does not support a causal link between acetaminophen (Tylenol) use in pregnancy and autism or ADHD. ACOG continues to state that acetaminophen is safe when used as directed in pregnancy. The observational studies suggesting a link have significant methodological proble...

Question 10

What actually helps you get pregnant faster?

Accepted Answer

The evidence-based strategies for getting pregnant focus on timing, not supplements or special diets. Tracking ovulation — through cycle monitoring, LH strips, or basal body temperature — and having sex in the fertile window (the 5 days before and day of ovulation) meaningfully increases per-cycl...

Question 11

Is gentle parenting evidence-based? Does it actually work?

Accepted Answer

Gentle parenting as a branded approach is not well-defined enough to have been rigorously tested as a complete system. However, the core elements it draws on — warm, responsive parenting, validation of emotions, and firm-but-kind boundaries — are well-supported by decades of developmental psychol...

Question 12

Is co-sleeping safe? What are the risks of bed-sharing with a baby?

Accepted Answer

Co-sleeping carries measurable risk for SIDS and accidental suffocation in infants, particularly under 4 months. The AAP recommends against bed-sharing for this reason. However, the risks are not uniform — they are dramatically elevated by specific factors (parental smoking, alcohol use, soft bed...

Question 13

Are food dyes dangerous? Do they cause hyperactivity in kids?

Accepted Answer

The evidence on food dyes and hyperactivity is mixed and modest. A 2007 UK study (the McCann study) found that a mixture of artificial food colors plus sodium benzoate increased hyperactivity in both 3-year-olds and 8/9-year-olds — but the effect was small and the study used a mixture of dyes, ma...

Question 14

Are white noise machines safe for babies? Can they cause hearing damage?

Accepted Answer

White noise machines are safe for babies when used at appropriate volume levels and distance. The evidence supporting white noise for improving infant sleep is positive, and there is no good evidence linking typical-use white noise to developmental delays or hearing damage.

## Evidence Summary

Question 15

What is the best sleep training method? Is cry-it-out better than Ferber?

Accepted Answer

The data does not clearly favor one sleep training method over another. Cry-it-out (extinction), Ferber (graduated extinction), and more gradual ‘fading’ methods all work. The best method is the one parents can follow consistently — the evidence points to parental consistency and infant temperame...

Question 16

Is it genetically possible for some men to only have boys or girls?

Accepted Answer

At the population level, the probability of having a boy or girl is essentially fixed at about 51% boys and 49% girls, and there is no strong scientific evidence that individual men are genetically predisposed to produce only boys or only girls. Families with several children of the same sex are ...

Question 17

How bad are ultra-processed foods? What does the evidence say?

Accepted Answer

The evidence associating ultra-processed food consumption with negative health outcomes is consistent across many large observational studies, but the causal story is complicated. Ultra-processed foods tend to be energy-dense, nutrient-poor, and engineered for overconsumption — but it is not clea...

Question 18

Is it safe to drink alcohol during the two-week wait before a pregnancy test?

Accepted Answer

During the two-week wait, the embryo operates on an ‘all-or-nothing’ principle in the first days after fertilization: if enough cells are damaged, the embryo will not implant; if the embryo does implant, it was not meaningfully harmed. This does not mean heavy drinking is safe, but it does mean t...

Question 19

When should you start potty training and what actually works?

Accepted Answer

The evidence on potty training timing and methods is surprisingly thin. Most pediatric guidance recommends following readiness signs (typically 18–30 months) rather than training at a fixed age. Both gradual and intensive (‘3-day’) methods appear to work for ready children, with readiness being t...

Question 20

What can I eat and drink while breastfeeding?

Accepted Answer

The data does not support most dietary restrictions during breastfeeding. There is no strong evidence that foods like dairy, caffeine, or spicy food reliably cause colic or fussiness in breastfed babies. Moderate caffeine intake is considered safe, and alcohol passes into breast milk at very low ...

Question 21

Is it safe for people to kiss newborn babies?

Accepted Answer

Kissing newborns on the face carries real but manageable infection risk, primarily from HSV-1 (oral herpes), RSV, and other respiratory viruses. The risk is highest in the first 6–8 weeks of life, when a baby’s immune system is least developed. Practical guidance: avoid face kisses from non-prima...

Question 22

Do I need expensive prenatal vitamins or will a basic one work?

Accepted Answer

The evidence does not support paying more for expensive prenatal vitamins. The key nutrients — folic acid (400–800mcg), iron, iodine, DHA, and choline — are what matter, and most can be obtained from a basic prenatal plus a DHA supplement. The marketing around premium prenatals vastly outpaces th...

Question 23

Is it safe to drink alcohol while pregnant?

Accepted Answer

Heavy drinking during pregnancy causes well-documented harm, including fetal alcohol syndrome. The evidence on light or occasional drinking is far less clear — most studies find no detectable harm from 1–2 drinks per week, but these are observational and cannot rule out small effects. The ‘no kno...

Question 24

Is day care bad for children's development?

Accepted Answer

The overall evidence does not support the claim that day care is bad for children. The literature shows small, mixed effects — some studies find modest increases in behavioral issues in low-quality care, while others find cognitive benefits from high-quality settings. Quality of care matters far ...

Question 25

Does sleep training harm babies or cause attachment problems?

Accepted Answer

The evidence consistently shows that sleep training does not harm babies or damage parent-child attachment. Multiple randomized controlled trials find that sleep training improves infant sleep and reduces parental stress, with no adverse effects on child behavior, emotional development, or attach...
