Anyone who mentions rods or backs is talking nonsense!
I would forget about routines for at least 3 months, they change so much. Just meet his needs quickly and consistently, comfort him, feed on demand and you're laying the foundations for a happy, confident child.
Personally I found my ds fell into more of a routine (that is, predictable feeding and sleeping rather than a routine I read in a book) at 4-5 months. At 5 months he started napping more in his cot, whereas up til then it was mostly in my arms/bed or in the sling/pram.
At 5 months I also stopped feeding him to sleep at bedtime, and instead we rocked him to sleep, then moved onto just shushing and patting him and a bit of pick-up/put-down. He didn't start self-settling til about 7 months and now at 10 months goes into his cot awake, self-settles and sleeps through the night (mostly!).
There's no rush, and in the early weeks I think it's easier to enjoy your baby by just going with the flow, feeding him when he's hungry, letting him sleep whenever and not watching the clock and worrying about what he should be doing. Invest in a good sling/wrap and you can mostly just get on with things.
