Here's a piece of parenting arbitrage almost nobody exploits: the bedtime story ritual β the one you'll want desperately at ages three, five, and seven β isΒ easiest to install at an age when the baby can't object, negotiate, or even notice. Baby books in month one aren't about the baby's experience. They're about laying rail.

Why early installation wins
Every habit fight you'll ever have at bedtime β the stalling, the screen negotiations, the "I don't want a story" contrarian phases β is a fight about changing the routine. A routine that predates the child's memory isn't a rule; it's physics. The toddler who has never known a bedtime without a book doesn't negotiate the book's existence, any more than they negotiate the existence of the crib. The infant sleep guidance at HealthyChildren.org has long recommended consistent bedtime routines from the early months β feed, bath, book, bed in some stable order β precisely because the sequence itself becomes the sleep cue.
The month-one version
Absurdly minimal: after the evening feed or bath, one short board book β two to four minutes β read in the dimmed room, in the low slow voice, ending with the same closing line every night. The baby is possibly asleep, definitely not following. Irrelevant. You're not performing for the audience; you're wearing the groove.
How the ritual grows on its own rail
Month three: the baby starts orienting to your voice at book time. Month eight: the book gets grabbed (see: book-eater era β read on anyway). Fifteen months: they bring you the book. Two years: the story matters. Three years: the characters matter. Five: the chapter cliffhanger matters. The slot never changed β same place in the sequence, same dimmed room, same closing line β while the payload upgraded from a black-and-white pattern book to a serialized season. Families who laid the rail early describe the whole progression as frictionless; the only decisions were ever about which book, never about whether.
The two protections
Guard the slot from day one against its two natural predators: exhaustion (the shrink-never-skip rule applies from infancy β one page counts) and the screen creep (the dimmed-room-book slot never shares billing with a device). A protected slot in year one is a fortress by year four.
