Okay, so mother-writers, or really just mothers or primary care takers of babies, what are the rites of passage, like the moments that no one tells you about but that are so profound they alter who you are?

So far I have:
The Night the Baby Won’t Stop Crying and You Lose it, First Stomach Flu, Holding Down Your Kid for a Blood Draw or other painful medical intervention, Losing Your Temper and Yanking their Arm and Realizing You are a Monster, First Time Child Physically Hurts You

There is also the important category of Think You Are Getting the Hang of This then Sleep Regression
