As someone with a six month old, there is no thriving. I was a zombie for the 4 months or so, and we’re lucky. Our baby started sleeping through the night at three months.

My sleep has not recovered, and I don’t expect it will for a few years. On the other hand, I’m not going out drinking anymore, or staying out late, so all those hangovers mornings I used to have don’t happen anymore, and I think that just cancels out the sleep deprivation.
