Months leading up to baby? Doctor's appointments increasing to weekly, potential health issues that impact work and life.
Month 1? Way less organized: pretty much random bands of sleep, feed, care throughout the 24h cycle.
Month 2? I would love to meet the parents who get 8 hours of sleep in Month 2.
Month 3–6? Yeah, getting better, but still a lot of chaos.
Oh, and this is 7 days a week. No Friday nights or weekends, folks.
Having a kid is a massive life change, and a massive commitment. I emphasize this for two reasons. 1) We as a working society still massively under-support working moms (and dads). And 2) I don't want anyone getting depressed when their post-kid life isn't nearly as organized as the one laid out here.
(Inevitable disclaimer: Am man supporting a 8-month pregnant, working partner, along with two other kids.)
