Why routines matter

Asked for the one thing parents should know, a scientist I deeply admire needed a single word. What it means, and how to keep routines steady without turning them into a cage.

Short answer: Routines give a young child certainty. When she can tell what is coming next, her attention goes to learning instead of bracing for surprises. Bedtime, meals, bath and reading are where that sense of predictability is built. What counts is a familiar order of steps, repeated and adjusted to your child, not a strict clock.

One word from Phil Fisher

Phil Fisher directs the Stanford Center on Early Childhood. During a Frontiers of Innovation and Harvard Center on the Developing Child meeting in Monterrey, I persuaded him to spend half an hour at the Kinedu offices. Diego, our chief technology officer, asked what he would tell parents if he could recommend just one thing. Phil answered immediately: predictability.

His reasoning: a child who knows what happens next doesn't spend energy on vigilance, so that energy goes into exploring and learning. In Phil's view, as I recount in Chapter 5, it is "the single most important thing a parent can provide." Routines turn a child's trust that you will show up into something she can anticipate, day after day (see You are the buffer).

What makes a routine work?

Not elaborate steps, and not a stopwatch. Sameness. The evening sequence, a shared meal at roughly the same hour, a bath that leads toward bed, a book every night: the value lies in the order repeating until your child can predict it.

Predictable is not rigid. Each of my four daughters needed something different. On feeding schedules or sleep-training methods, experts disagree and families differ; pick what fits yours. Travel, teething, illness and developmental leaps will knock routines off course. That's normal. The skill is coming back to them.

Bath time is a small ritual that often flows straight into sleep; see why bath time is not just bath time.

Why sleep is where routines pay off most

As sleep researcher Rebecca Spencer, who taught a sleep course for us, confirmed, missing even an hour or two noticeably weakens a young child's ability to manage her emotions: a dropped spoon can feel like a catastrophe.

A study that tracked 1,492 children from two and a half to six found that short sleep before about 41 months was associated with more hyperactivity and impulsivity and lower vocabulary scores at school entry, even after accounting for family factors. That is a correlation, not proof of cause.

If sleep problems persist despite a steady routine, talk to your pediatrician. Sometimes there is a physical cause that no routine can fix.

Honest about the hard part

Holding the bedtime sequence on nights you'd rather collapse on the couch is hard. Doing it anyway is one of the quiet ways of loving your child. You don't need to be perfect. You need to be consistent. The Routine Builder can help you turn your evenings into a simple sequence.

The full why

Predictability is the fourth invisible force in Big Bang Baby, the one that turns play, relationships and a calm response to stress into daily habit. The full why, including what sleep research says about naps and bedtime, is in Chapter 5. You can read the Introduction free.
