My first baby was barely a week old, and already some misguided fool asked me, "So, is he in a routine yet?"
"Are you mad?! Of course not!" (OK, I never actually said this, I'm much more timid in real life than on paper. But that's what I was thinking.)
Why are people so obsessed with routine? I suspect it's because our lives are governed by the clock, rather than by the sun, the seasons and our bodies. We have become obsessed with numbers and measuring and quantifying things, and now we want babies to be ruled by the clock too. The thing is, babies are ruled by their biology, by their basic needs, and they don't give a damn about your clock.
Here's a newsflash for you: Forget about "getting your baby into a routine"!
