Medical guidance changes, studies get replicated (or don't), and guides go stale quietly on
most sites. Not here: every meaningful update to our content and tools is listed below, newest
first. If a guide changed because the official advice changed, this is where you can see it.
July 17, 2026
Added month-by-month pages (months 1–12) alongside the weekly pages.
Added a unique "this week, specifically" fact to each of the 52 weekly pages.
New pages: the preemie hub, For grandparents, and an honest comparison with The Wonder Weeks.
Added 3 a.m. mode: a warm dark theme with larger text, for one-handed night reading.
The forecast now remembers your baby's dates on your device (local storage, not cookies — privacy policy updated accordingly), with a "forget these dates" button.
Reworded the top statistics bar: replaced audience claims with verifiable ones.
July 10, 2026
Launched the 52 weekly pages (/week/1 to /week/52), each with the CDC checklist for its window.
July 7, 2026
All five window guides fact-checked and marked "Last verified: July 7, 2026".
July 6, 2026
Site launch: the Fussy Phase Forecast with adjusted age, five window guides, and the fact-checking policy published.
How updates happen: sources are re-checked against CDC, NHS and AAP publications, and guides
carry a "last verified" date. The method is documented in
how we check our facts.

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.
