The clocks just fell back an hour and my

Short answer: your baby hasn't changed — the label on the clock has. After "fall back," the sun and the light cues that set your baby's clock arrive an hour earlier *on the clock face*, so the same morning that read 6:00 now reads 5:00. To get the number back, you have to delay the baby's clock about an hour — and the lever that does most of the work is keeping the room dark until the target wake time, then giving bright light right after, not keeping it bright at dawn.

This is the schedule-mismatch fork (clock change + light timing), not the "can't fall asleep at night" fork and not a settling/association problem. One hour on a 15-minute-per-3-days pace takes about 12 days, so expect it to look lumpy for a week.

1) What you tried vs. the better alternative

Tonight's three moves (under 25 min total):

1. Write the target on the fridge: "06:00 — dark until then, light after." Bedtime tonight = the same clock number you used before the clocks went back. No earlier.
2. Set up the dark now (5 min): blackout curtains/blanket over the window, no night-light that glows, phone face-down outside the bedroom, sibling's screen off. Wind-down chain unchanged: pyjamas → feed → one or two books → dark → down. Same order as every night.
3. Set up the morning (5 min): breakfast that needs no cooking (things you already have — toast/egg/yogurt/oatmeal, fruit), and a plan for the 6:00 walk being the school run. Put the school bag and shoes ready the night before so the 6:00 start isn't a scramble.

Overnight rule (this is the whole trick): 5:00 wake = dark, quiet, boring. No lights, no talk, no play, no screens. If a feed is due (your own schedule), keep the room as dark as possible and go straight back down. If baby is fully awake and won't settle, start the day *quietly* — low light, no screen, food at home — and don't push bedtime earlier tomorrow because of it.

Shift table (put next to the fridge):

Household scripts (screenshot these):

• *To the adult/elder in the house:* "From tonight, if the baby is up before 6, keep the room dark and curtains shut. No TV or hall light before 6. At 6 we open the curtains and go outside."
• *To whoever does the school run:* "Morning is dark until 6 — could you take the 6:00 walk and let me sleep until then for the first few days?"
• *To the sibling in the room:* "Night light off, no screens after bedtime, no waking the baby up."

This week's anchor (one sentence): *Every day this week, including weekends, the house stays dark and quiet until 6:00 on the clock, and the first outdoor light of the day happens after 6:00.*

Record or clinic: this is a week to record. Send me the wake time and each nap time on your mornings and I'll keep a 7-day log and print a one-page table you can hand to the pediatrician if this doesn't settle. I'd also hold a daily 5:45 "keep it dark until 6" and 6:00 wind-down nudge — tell me your city/timezone (your clock just moved, so I don't want to guess) and I'll set them.

2) Constraints / avoid list

• No melatonin, magnesium, "sleepy tea," herbal gummies, or anything bought online for the baby — none of these are ours to decide, and none come with a baby-safe answer. If you want to ask about melatonin, that's a pediatrician/pharmacist conversation; we won't dose or guide dosing.
• Don't move bedtime earlier to "tire the baby out" — it backfires into earlier waking.
• Don't keep the room bright at dawn, and don't use a screen as a pacifier at 5:00.
• Don't cut or skip naps to force the 6:00 wake.
• Don't change anything about feeding volumes, or any medication — this is a clock problem, not a feeding or medicine problem.
• Safe-sleep rules don't bend for a 5:00 baby: baby on their back, on a firm, flat, non-inclined surface, in their own cot/bassinet with no pillows, duvets, loose blankets, soft toys or bumper pads; room-share, not bed-share; keep the sibling out of the bed. Never settle or feed on the sofa or armchair — at 5:00 with a foggy adult this is the most likely accident of the week, and it's also a red flag. If anyone has had alcohol, smoked, or taken anything drowsy-making, the baby must not be in that bed either.
• No sleepy driving — if you're up at 5:00 and driving the school run, arrange the ride instead.

3) Red flags — when to stop DIY and get help

Urgent, today: baby stops breathing or pauses and gasps while asleep, or lips/face turn blue or grey in sleep → call your local emergency number now. No number I can safely guess from here — use your local emergency service.

Same-day clinic visit: fever in a baby under 3 months; fast or laboured breathing; floppiness or hard to wake; refusing feeds; noticeably fewer wet nappies; unexplained weight loss; persistent inconsoliable crying; or a new pain sign (ear-pulling, pain with teething, reflux, a new rash). Early waking that comes with pain, illness, or a growth spurt is a body problem, not a clock problem.

For you, not the baby: if you're falling asleep holding the baby, nodding off at the wheel, or thinking "I can't keep going" — that's the point to call your own doctor or a support line, and to hand the 5:00 shift to another adult tonight.

Decision tree (screenshot):

```
Baby up before 6:00
├─ Light in the room? → FIX THE CURTAINS FIRST. Biggest lever, free, tonight.
├─ Won't resettle, fully awake? → quiet start to the day (low light, no screen).
│ Do NOT move bedtime earlier tomorrow. Do NOT cut naps.
├─ Woke at 5:00 after an early/last nap ending late? → restore the nap; keep same lengths.
├─ Snoring, breathing pauses, gasping, blue in sleep, or your own exhaustion,
│ or any pain/illness sign? → clinic / emergency now, not a light experiment.
└─ Otherwise → keep the 06:00 anchor, log it, review in 7 days.
```

What success looks like in 24 hours (no cure promised): tomorrow morning, either baby sleeps through the 5:00 window or is resettled without starting the day — and you still got one unbroken block before the school run. That's it. The 6:00 target usually needs 3–12 days of consistent dark-then-light; expect a couple of louder mornings on the way, and treat any morning where the 6:00 wake happens as a win, not a failure.
