The first few months (hell, first year) of motherhood was such a blur that I honestly don't know how I got through it with my sanity. Like others said before me, there's no ordinary job that has the level of stress combined with sleep deprivation and physical recovery from giving birth/being pregnant/nursing that compares to taking care of a newborn. The physical component is way more intense - and takes longer - than people who haven't been through it can even imagine.
