My 4-month-old still wakes twice a night

Question
My 4-month-old still wakes twice a night—when do babies actually sleep 11 hours straight without sleep training? Real household: caregiver juggling school week and one elder or sibling nearby. Schedule: Wed bedtime 19:30, feeds ~00:15 and 04:00; I'm back at work Mon. Kitchen/home right now: bedside bassinet, white-noise app, feeding log on phone. Already tried: compared her to friends' babies online and panicked. Please answer as a practical family-care guide: what to do next tonight/today, what to avoid, and a clear decision tree. Constraints: respect «No diagnosis, no medication changes»; no dosing kids/pets/elders yourself; no mystery powders or buying prescription meds online; keep steps screenshot-friendly under ~25 minutes where cooking/care applies. Structure your help as (1) what I already tried vs better alternatives, (2) constraints/avoid list, (3) red flags—when to stop DIY and get clinical/urgent help. Keep the voice concrete and kind for a tired caregiver; stay inside kitchen/home-care/communication levers only. Name what success looks like in 24 hours without promising cures. Avoid brand shopping lists; focus on routines, food already at home, and communication scripts caregivers can screenshot.
Réponse
Honest answer first: most babies are not developmentally ready to "sleep through" 11 hours straight until past12 months. Two feeds at 4 months is normal infant sleep, not a problem to fix. Sources at bottom.

(1) What you already tried vs better alternatives tonight
| You tried | Better alternative |
|---|---|
| Compared her to friends' babies online and panicked | Put the phone face-down after feeds. The phone is the comparison engine — not the baby |
| Searched for the magic age she'll "sleep through" | Aim for the back-to-sleep path, not zero wakes: same room, same bassinet, same low light |
| Kept the bedside bassinet (good) + white-noise app (fine) | Keep both. Don't add swings, wedges, rolled towels, or incline — flat firm surface only |
The lever at 00:15 and 04:00 is the sleep association — what you do in the first minute back. A baby who goes into her bassinet drowsy-but-not-asleep learns the bassinet is the place sleep happens. A baby who only ever falls asleep on you or only after a long rocking cycle needs that cycle at every wake.
(2) Tonight / today — under 25 min
Bedtime chain (same order, ~20 min): pyjamas → feed → song or one short book → bassinet drowsy but not asleep → white-noise on. Same chain tomorrow, and the day after.
At each wake (00:15, 04:00):
- Bassinet stays in the room, lights stay low — no overhead, no scrolling.
- Feed.
- Nappy only if wet/soiled — don't unwrap for the sake of it.
- Back to bassinet drowsy-but-not-asleep.
- You leave. No lingering.
Helper script (sibling / elder / school-age): screenshot this and pin it where they make tea.
- Night feeds are caregiver's job (breast/bottle).
- Helper's job is the morning block so caregiver rests after the 04:00 feed.
- "Calm her with the bassinet, not in your bed." Helper can pat, shush, hand baby back. No sofa, no propping the bottle, no carrying her around until she sleeps.
(3) Avoid list — keep this open on the fridge
- No sleep training for a 4-month-old. Methods aimed at infants aren't developmentally matched and unsafe versions (extinction, bed-sharing to "extend sleep") raise risk.
- No rice cereal, formula thickener, or "heavier stomach" remedy in her bottle. No evidence it lengthens sleep; choking risk.
- No propping, no pillows / duvets / bumpers / soft toys in the bassinet. Flat, firm, empty, on her back, every sleep.
- No bed-sharing to extend your sleep. Soft mattress, adult bedding, and adult sleep raise risk. If you feel yourself dozing on the sofa with her — put her down in the bassinet first, then sit.
- No melatonin, diphenhydramine, or sleep aids for you while breastfeeding unless your doctor or pharmacist has signed off.
- No more baby-comparison scrolling — that's the panic generator, not information.
(4) Decision tree — when DIY stops
| This happens tonight or this week | Stop DIY and do this |
|---|---|
| Pauses in breathing, or she turns blue/pale, or is working hard to breathe (ribs sucking in, grunting) | Local emergency number now. Don't wait. |
| Fever 38 °C+ under 3 months, or any fever that won't come down | Same-day clinician call |
| Refusing feeds, fewer than 6 wet nappies/day, or weight crossing lines down | GP / health visitor / paediatrician this week |
| Wakes every 30–60 min for nights and you cannot function, or thoughts of harming yourself or her | Local crisis line or ED tonight — your safety matters too |
| Two feeds, 19:30 bedtime, both wakes back-down within ~25 min | Stay the course. That's the median for 4 months. |
What success looks like in 24 hours
- Both feeds done in under 25 min each — no unwrapping, no relatch-athon, no scrolling.
- She goes back into the bassinet drowsy, not asleep, three nights in a row.
- You sleep at least one 3-hour block between 00:15 and the next wake.
- Comparison apps stay closed after feeds.
That's the win. "Slept through" is not on the menu at 4 months and that's normal.

Hand off. Routine weight, feeding and milestone reviews belong to your GP / health visitor / paediatrician — not to a comparison app. Anything in the red-flag table above stops home coaching tonight; your local emergency number or same-day clinician is the next step, not the internet.
