why late bedtime backfires
Once a baby pushes past the point their body wanted to sleep, they get a chemical second wind, cortisol, the stress hormone that keeps them going. So the extra thirty minutes you spent winding them down were working against you, because their body was gearing up, not down. That is why an hour of rocking, shushing, and starting over so often ends in a more wired baby, not a sleeping one.
the earlier move
The fix most people never try is bringing bedtime earlier, sometimes meaningfully. A baby put down before the overtired cortisol spike settles faster, not slower. It sounds wrong. It usually works, and the effect can show up in a day or two.
the routine is the cue
The other lever is the same short, boring sequence every single night, in the same order. Not a longer routine, a consistent one. The predictability itself becomes the signal to the body that sleep is coming, which does more than any single step in it. A rhythm, not a schedule.
If bedtime distress seems like pain rather than protest, that is one for your pediatrician.
quick answers
Why does my baby fight bedtime so hard?
Usually bedtime is landing too late. Past a certain point the body releases cortisol, a second wind, and a wired baby fights settling. It feels backwards but earlier often fixes it.
Should bedtime be earlier or later if my baby won't settle?
Almost always earlier. A baby put down before the overtired spike settles faster, not slower.
How long should a bedtime routine be?
Short and identical every night beats long. The consistency of the sequence is the cue for sleep, not the length of it.
