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
Start with the basic checks: feeding, nappy, temperature, clothing, and anything that could hurt. If the cry sounds unusual, your baby is hard to wake, or breathing looks different, get medical help. If you feel overwhelmed, put the baby on their back in a safe cot and step away for a few minutes.

38C / 100.4F or higher is a fever. If your baby is under 3 months, call a medical professional now. At any age, get urgent help if your baby is hard to wake, struggling to breathe, having a seizure, or looks blue or grey.

Frequent night waking is common in the first year and does not mean you have caused a problem. For every sleep, place your baby on their back on a firm, flat, separate sleep surface with no pillows, bumpers or loose bedding.

Spitting up after feeds is common. Get medical help promptly if vomit is green or bloody, vomiting is repeatedly forceful, your baby struggles to breathe, feeds poorly, or has noticeably fewer wet nappies.

Many baby rashes are mild, but a rash needs prompt medical attention if your baby also has a fever, feeds poorly, is hard to wake, or seems very unwell. Call emergency services if there is trouble breathing or swelling around the lips or tongue.

A red face and straining do not mean constipation if the poo is soft. Hard, dry poo is different. Contact a medical professional if your baby is very young, feeds poorly, vomits, has blood in the stool, or has a swollen tummy.

Sore gums, drooling and chewing are common signs. Teething does not explain a fever of 38C / 100.4F or a baby who seems very unwell, so do not assume a new tooth is the cause.

A yellow tint in the first week is common. Get medical help promptly if it appears in the first 24 hours, or if your baby is hard to wake, feeds poorly, has dark pee or pale poo, or is becoming more yellow.

Put the baby on their back in a safe cot, leave the room for a few minutes, and ask another adult to take over if one is available. If you think you may hurt yourself or the baby, call your local emergency service now.

Wanting to be held is common in young babies. Contact sleep is only safe while the adult stays awake. Never fall asleep holding a baby on a sofa or chair. For sleep, use a firm, flat, separate surface and place the baby on their back.

A repeated fussy stretch in the evening is common in young babies, but the pattern is not a diagnosis. Get medical help if there is a fever, breathing looks different, your baby is hard to wake, or feeding has changed sharply.
