The current ethos of "everyone has kids, I want one too", without severe consideration given to the potential health, development, and quality of life of the human being being created from unhealthy or incapable parents is problematic, unethical, and inhumane.

Questions that every potential parent should be severely considering:

Are my body and mind really in peak condition, enough to create a high functioning, healthy human being who will not suffer from physical or mental disease? Do I have a good enough understanding of human health and development to make this judgment? Am I able to grasp the systemic outcomes of a majority of the population being unhealthy and continuing to use their bodies to create children?

Age of mother:

Autism risk is 18% higher for children born to teen moms than moms in their 20s, compared to 15% higher for children born to moms over 40 (2015): http://www.npr.org/sections/health-shots/2015/06/10/413205921/more-evidence-that-parents-ages-could-influence-autism-risk

Most previous research suggests that the older women are when they give birth, the greater the health risks are for their children. Childbearing at older ages is understood to increase the risk of negative pregnancy outcomes such as Down syndrome, as well as increase the risk that the children will develop Alzheimer's disease, hypertension, and diabetes later in life. A new study presents contrary evidence (2016): https://www.mpg.de/10411999/older-mothers-fitter-kids

Incidence of Down Syndrome rises dramatically after the mother turns 30: http://i2.wp.com/www.downsyndromeprenataltesting.com/wp-content/uploads/2013/07/AAFP-DS-prevalence.jpg

Significantly greater overall mortality occurred in infants born to mothers younger than 20 (compared to mothers 30-34) (1983): https://www.ncbi.nlm.nih.gov/pubmed/6886903

Teenage pregnancy was associated with a significantly higher risk of PIH, PET, eclampsia, premature onset of labor, fetal deaths and premature delivery. Increased neonatal morbidity and mortality were also seen in babies delivered to teenage mothers. Younger teenager group (17 years) was most vulnerable to adverse obstetric and neonatal outcomes (2007). https://www.ncbi.nlm.nih.gov/pubmed/17978452

Teenage mothers had better obstetric outcomes, despite the higher incidence of preterm labour, and that young adolescents (<17 years) performed as well as their older peers (1998): https://www.ncbi.nlm.nih.gov/pubmed/9853885

Kids born to older moms and dads (40s & 50s vs 20s) have higher rates of autism (2015): http://health.usnews.com/health-news/patient-advice/articles/2015/06/17/study-parents-ages-linked-to-autism-risk

Men are increasingly having kids at older ages in the U.S., but doctors say that comes with health risks for the babies, including prematurity and birth defects. https://www.nbcnews.com/health/parenting/health-risks-babies-older-fathers-al-pacino-expecting-child-rcna87237

Baby food:

95 percent of baby foods tested contain toxic metals (Oct 2019) https://www.nbcnews.com/health/kids-health/new-report-95-percent-baby-foods-tested-contain-toxic-metals-n1068306 For nearly 90 percent of the baby foods tested, the FDA has not issued guidance or set standards for the maximum safe limit of heavy metals, according to the report. "The FDA should be doing more," Brody said. "It's the FDA’s job to set rules that make food safe."

New report finds toxic heavy metals in popular baby foods. FDA failed to warn consumers of risk. Gerber, Beech-Nut, HappyBABY and Earth’s Best Organic baby foods contained arsenic, lead, cadmium and mercury, report found (Feb 2021): https://archive.vn/3ph7o#selection-1565.10-1569.0 - Response to Emily Oster: https://archive.vn/H6Q1x#selection-1559.10-1559.11.

Lead found in 20% of baby food samples, especially juices and veggies. The baby food versions of apple juice, grape juice and carrots had detectable lead more often than the regular versions (2017): http://www.cnn.com/2017/06/16/health/lead-baby-food-partner/index.html

It may be safer to use whole foods, and source spices from trustworthy sources that test them for contaminants like heavy metals and publish the test results.

Breastfeeding:

The American Academy of Pediatrics recommends that infants be exclusively breastfed for about the first 6 months with continued breastfeeding alongside introduction of complementary foods for at least 1 year, but only 25% of US infants meet this goal https://www.cdc.gov/breastfeeding/data/reportcard.htm

The American Academy of Pediatrics' publication also lists numerous health outcomes, for both the infant and mother, associated with breastfeeding: https://pediatrics.aappublications.org/content/129/3/e827 - "Given the documented short- and long-term medical and neurodevelopmental advantages of breastfeeding, infant nutrition should be considered a public health issue and not only a lifestyle choice"

The American Academy of Pediatrics issued a policy statement Monday that extends the period of time for which breastfeeding is recommended to two years or more (Jun 2022) https://www.nytimes.com/2022/06/27/well/family/breastfeeding-age-guidance.html

A few studies haven’t found a tie to cognitive capacity, but most have. Over all, a new review of 17 studies found a mean gain of three I.Q. points for children who were breast-fed: http://www.nytimes.com/2015/10/22/opinion/the-miracle-breast-milk-elixir.html – A recent survey by Acta Paediatrica of 130 estimates found that breast-feeding promotion on average increased exclusive breast-feeding by an astonishing 44 percent.

Breastfeeding duration is associated with improved cognitive scores at ages 5 through 14, even after controlling for socioeconomic position and maternal cognitive ability (May 2022, n=7,855) https://neurosciencenews.com/breastfeeding-cognition-20663/ To what extent does confounding explain the association between breastfeeding duration and cognitive development up to age 14?

Improved Estimates of the Benefits of Breastfeeding Using Sibling Comparisons to Reduce Selection Bias (2005): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1361236/ "Nearly all of the correlations found in the between-family model become statistically insignificant in the within-family model. The notable exception is a persistent positive correlation between breastfeeding and cognitive ability. This study provides persuasive evidence of a causal connection between breastfeeding and intelligence. However, it also suggests that nonexperimental studies of breastfeeding overstate some of its other long-term benefits, even if controls are included for race, ethnicity, income, and education."

Factors contributing to lack of breastfeeding:

At the most basic level, a woman is biologically evolved to create a vital early-life nutrition for their infant. If they cannot, there is clearly a biological deficiency.

Medical contraindications to breastfeeding are rare https://pediatrics.aappublications.org/content/129/3/e827

Virtually all factors contributing to lack of breastfeeding seem to be avoidable. Some are due to the mother's poor health, and others are due to the mother's poor health resulting in poor development of the infant: https://sci-hub.se/https://www.liebertpub.com/doi/full/10.1089/jwh.2014.5059

Most women make their feeding decisions before conception and/or during pregnancy. Receiving breastfeeding education before delivery is important. C-section and BMI are associated with breastfeeding rates. Can hand-express when birth is premature and infant is not able to breastfeed.

Starting on page 11/23 https://effectivehealthcare.ahrq.gov/sites/default/files/cer-210-breastfeeding-summary.pdf lists multiple poor health statuses which are associated with breastfeeding.

Infant feeding decisions seem to be made prior to, or irrespective of, contact with health professionals. Health promotion campaigns in the UK have been influential in their ability to educate women about the benefits of breastfeeding. However, this did not dissuade participants from formula feeding once their decision was made. The desire for paternal involvement also seemed to be another influential factor. Some of the formula feeding women expressed a strong desire to re-establish their identities as separate individuals and as ‘non-mothers’."

Preconsiderations:

Antinatalists would benefit from discussing the longevity movement with natalists. Lots of the reasons natalists give for creating children have to do with the natalist dying. Dying will soon become avoidable, and creating offspring will cease to become the default. The sooner this change occurs the better.

Some of the major problems:

We've already depleted the oceans of fish, replaced them with plastic, oil, heavy metals and other industrial pollution. We're doing tremendous damage to nature, such as causing massive deforestation, killing coral reefs, and more. Causing the extinction of a huge variety of animal species. Climate change threatening both our survival and the survival of huge portion of animals and habitats on our planet. Extreme animal suffering due to horrendous factory farming conditions and habitat destruction. And causing a huge amount of human suffering, much of which comes from the rises in chronic disease and poor health, both of which have been increasing drastically in recent decades. The vast majority of people now are nowhere near healthy enough to be ethically using their bodies to create other people.
