What’s happening at this stage
Welcome to the big one: around four months, your baby’s sleep architecture matures permanently — adult-like sleep cycles arrive, and with them, more visible wakings between cycles. If sleep suddenly fell apart, you’re probably in the 4-month sleep regression, not doing anything wrong.
Structure starts genuinely helping now. Age-appropriate wake windows, a consistent wind-down, and practising falling asleep in the sleep space (drowsy but awake, when it works) all make the new sleep cycles easier to link.
Three things that help right now
- Hold steady during the regression — it’s a development, not a habit, and it passes.
- Guard the last wake window before bedtime; it’s the one that most often runs too long.
- Keep 3–4 naps for now; quality beats perfect timing.
