So, if Google is to be believed, the last three nights in a row have been part of the fourth wonder week. We’ve hit 16 weeks old and it seems we have entered this vortex of sleepless hell, the four month sleep regression – and worse, it supposedly can last five or six weeks. We were just getting the hang of waking up once overnight, and then up at six am. I was actually getting used to being an early bird. But now its a fight to go to sleep, and worse, a fight to stay asleep. My lovely placid baby has been replaced by this screaming, angry tiny tyrant. I am not a fan.
