Four regressions, what changes, and what to hold

A regression is the one time in baby sleep where the right move is usually to change nothing. The instinct is to fix it — new routine, earlier bedtime, back to rocking — and that's what turns a two-week phase into a two-month habit.

This toolkit covers all four regressions, tells you which one you're in, and is mostly about what to hold steady while it passes.
