There were the famous studies from a few years ago in Israel and Germany that sparked a small cultural spat in the West about regretting motherhood and having a child being a source of immense unhappiness.[1][2] It's of course obvious why they generated so much outrage, centuries of propaganda about motherhood being bliss and the highest calling for women.

To quote from the WaPo article below (some people may not be able to read it):

"it turns out that having a child can have a pretty strong negative impact on a person's happiness, according to a new study published in the journal Demography. In fact, on average, the effect of a new baby on a person's life in the first year is devastatingly bad — worse than divorce, worse than unemployment and worse even than the death of a partner."

"Researchers Rachel Margolis and Mikko Myrskylä followed 2,016 Germans who were childless at the time the study began until at least two years after the birth of their first child. Respondents were asked to rate their happiness from 0 (completely dissatisfied) to 10 (completely satisfied) in response to the question, "How satisfied are you with your life, all things considered?""

"On average, new parenthood led to a 1.4 unit drop in happiness. That's considered very severe. To put things in perspective, previous studies have quantified the impact of other major life events on the same happiness scale in this way: divorce, the equivalent of a 0.6 "happiness unit" drop; unemployment, a one-unit drop; and the death of a partner a one-unit drop."
