Do to lactational amenorrhea, mothers who breast feed their kids until age 2 (as the World Health Organization recommends) are much less likely to get pregnant

Do to lactational amenorrhea, mothers who breast feed their kids until age 2 (as the World Health Organization recommends) are much less likely to get pregnant again quickly enough to have kids spaced less than two years apart.
Considering that breast feeding (at all) is correlated with an 8 point IQ increase on average, the above could completely explain the study's findings.
- TheSOB88 15y agoCould be, but I bet the amount of people who breastfeed their kids for 2 years is dwarfed by the amount of people who don't, but due to chance have kids 2+ years apart.
- grandalf 15y agoCould be, but b/c gestation takes 9 months breast feeding would only have to take place for 13 months for lactational amenorrhea to result in the 2 year spacing. Based on a quick google search of breastfeeding rates, in the US 25% of women who breast feed do so until 12 months, which may be enough to create the difference noted in the study.
