No topic collects more myths, gadgets, and guilt than baby sleep. This hub is the sourced
version: what the NHS numbers actually say, what genuinely lowers SIDS risk, why the 4-month
"regression" is maturation, and what "sleeping through" really means. Short answers first,
sources on every page.
Almost certainly not. Newborn sleep is fragmented by design, fussy windows temporarily disrupt it, and sleep "maturing" at 4 months makes it choppier before it gets better. The research supports patience far more than it supports any particular technique.
What actually lowers SIDS risk?
Back sleeping, every sleep. A flat, firm, empty cot. Room sharing (not bed sharing) for the first 6 months. No smoking around the baby. These are the measures with strong evidence — details and sources in the safe sleep guide.
Do fussy windows ruin sleep?
They can dent it for a few days — parents in the original 1992 research reported temporary dips during fussy weeks. See where your baby is with the free forecast so a rough week has a name and an end.

Won't stop crying
Most crying jags pass. If it happens most days, in long stretches, especially evenings, that's often colic, and it is not something you caused. A quiet, dim room and slow rocking help more than trying something new.
Tested & works
The 5 S's, in order: snug swaddle, hold on their side in your arms, shush as loudly as they cry (or white noise), small fast jiggles, then something to suck. Used together they calm most crying babies within minutes.
100.4F / 38C or higher counts as a fever. Under 3 months with any fever: call your doctor now. Older babies who are still feeding and settling usually just need home care and watching, but your own concern is reason enough to call.
Tested & works
Dose paracetamol or ibuprofen by your baby's weight, not their age — it's the single most common dosing mistake. And don't bundle them up: one light layer helps the fever do its job.
Frequent night waking is normal for most of the first year. It is not a sign you are doing something wrong. A short, calm routine tends to help more than a long, elaborate one.
Tested & works
The same 3 steps, same order, every night (bath, feed, song), then into the cot drowsy but awake. In clinical trials this simple routine measurably improved infant sleep within 2 weeks.
Spitting up after feeds is common and usually harmless. It is worth a closer look if it is forceful, happens after most feeds, or your baby seems uncomfortable.
Tested & works
Keep your baby upright against your shoulder for 20–30 minutes after each feed, and try smaller, more frequent feeds. These two changes alone settle most spit-up — no wedges or thickeners needed.
Most baby rashes are mild and clear on their own. Dry, itchy patches are often eczema, which usually eases with simple changes long before it is something to worry about.
Tested & works
Soak and seal: a short lukewarm bath, pat (don't rub) mostly dry, then a thick fragrance-free emollient within 3 minutes, every day. It's the best-proven home treatment for baby eczema.
A red face and straining is not constipation if the poo comes out soft. Real constipation means hard, dry, pellet-like poo. More milk feeds (or cooled boiled water for formula-fed babies) usually help; see a GP early for a young baby.
Tested & works
Bicycle their legs gently and massage the tummy clockwise for a few minutes, a couple of times a day. On solids? The 3 P fruits — prunes, pears, peaches — are the proven natural laxatives for babies.
Sore gums, drooling and chewing on everything are classic signs, and they can start well before or after the average 6 months. Teething does not cause a real fever (38C/100.4F or higher) — look for another reason if your baby has one.
Tested & works
A chilled (not frozen) solid rubber teether, or a clean wet washcloth from the fridge to chew on. Skip numbing gels and amber necklaces — regulators warn against both.
A yellow tint in the first week is common and usually harmless, peaking around day 3. Get medical help promptly if it appears in the first 24 hours, or if your baby is hard to wake, feeding poorly, or has dark pee or pale poo.
Tested & works
Feed early and often — 8 to 12 feeds in 24 hours. Milk is what flushes bilirubin out, so frequent feeding is the proven way to help mild jaundice clear faster. Sunlight through a window is not a treatment.
Not knowing what to do is not failing. Every parent learns this on the job. Put the baby down somewhere safe, take two minutes for yourself, and come back when you feel steadier.
Tested & works
Crying never harms a baby — but shaking can. Baby safe on their back in the cot, door closed, 10-minute timer in another room. Pediatricians teach this exact routine because it works when nothing else does.
Wanting to be held is biology, not a bad habit — young babies can't be spoiled. It eases as they grow. Meanwhile, a snug swaddle (before rolling age) and white noise recreate some of that held feeling in the cot.
Tested & works
The tested transfer: carry your baby while walking for 5 minutes, then sit and hold them still for 5–8 more before laying them down feet-first, keeping a hand on their chest. Researchers found this sequence dramatically cuts wake-on-put-down.
Fussy, cluster-feeding, inconsolable from about 5 to 11 p.m.? That's the witching hour. It peaks around 6 weeks and fades by 3–4 months. It is normal, and it is not your milk or your parenting.
Tested & works
Get ahead of it: dim lights and lower the noise an hour before the usual meltdown, offer cluster feeds without watching the clock, and go for a walk with the baby in a carrier — motion plus your heartbeat is the most reliable evening reset.
Newborns are loud sleepers: grunting, squirming, even brief red-faced straining are usually just active sleep and an immature gut, not pain. It typically fades by 3–4 months.
Tested & works
The pause: when you hear grunting, wait a few minutes before picking up. Most babies are still asleep and will resettle — scooping them up mid-cycle actually wakes them. Get help if grunting comes with every breath, fever, or blue lips.
