Quick Answer: Baby sleep develops in stages: newborns sleep 14 to 17 hours in fragments, day-night rhythm emerges around 8 to 12 weeks, and regressions punctuate the first two years. Follow Health Canada safe-sleep rules at every stage: alone, on the back, in a bare crib. This Mattress Miracle hub maps each age, the gear, and the rough patches.
Baby sleep is the subject Brantford parents ask Mattress Miracle about with the most desperation in their voices, usually while shopping for a crib mattress on two hours of rest. Baby sleep refers to the developing sleep architecture of the first three years: newborn sleep is fragmented and evenly spread across day and night, circadian rhythm emerges over the first months, and consolidated night sleep arrives, with regressions, on its own uneven schedule. Mattress Miracle has fitted family sleep in Brantford, Ontario since 1997, and this Parents' Desk collects every baby and toddler guide we publish: schedules, regressions, safe-sleep rules from Health Canada and the Canadian Paediatric Society, and the honest version of what gear matters.
"Parents come in asking which crib mattress makes a baby sleep through the night, and I give them the truthful answer: none of them. What a good crib mattress buys you is safety and fit, firm, flat, and snug to the crib frame with no gap. The sleeping-through part is development, and it comes when it comes. I would rather lose a sale than let a tired parent believe foam density fixes a four-month regression."
Talia Grose, sleep specialist, Mattress Miracle
Safe sleep, in Health Canada's definition, means baby sleeps alone, on their back, in a crib, cradle or bassinet that meets Canadian regulations, with a firm flat surface and nothing else in the sleep space: no blankets, bumpers, pillows or toys for the first year. Every guide in this hub builds on that baseline.

Baby sleep by age: what is normal right now
Baby sleep norms shift fast, and knowing the current normal prevents most 3 a.m. panic-searching. The newborn sleep schedule guide covers the fourth-trimester reality: 14 to 17 total hours in two-to-four-hour fragments, day-night confusion, and why none of it is a problem to fix. From there, wake windows by age gives the awake-time ranges that make naps land instead of fight, and infant sleep temperature answers the overdressing question every Canadian winter parent asks. When night feeds consolidate and you are weighing formal approaches, the Ferber method guide explains graduated checks without the internet shouting match, including when paediatric guidance says wait.
When do sleep regressions happen?
Sleep regressions are temporary sleep collapses tied to developmental leaps, and they arrive on a rough schedule: around 4 months (the big one, a permanent change in sleep architecture), 8 to 10 months, 12 months, 18 months and 2 years. The sleep regressions guide maps every age, how long each lasts (research suggests two to six weeks when routines hold), and the difference between a regression and a schedule problem wearing a regression costume. Dedicated deep-dives on the 4-month and 18-month regressions are in production for this hub. For the crying that is not a regression at all, our newborn snoring guide covers the night noises that are normal and the ones worth a doctor's ear.
The four-month regression is not a regression
At around four months, a baby's sleep permanently reorganizes into adult-style cycles with light and deep stages. Studies indicate the frequent wakings that follow are the new architecture, not a phase that reverses: babies now surface between cycles and need to fall back asleep. That is why paediatric sleep guidance focuses on independent settling from this age. This page supports, and never replaces, advice from your paediatrician or the Canadian Paediatric Society.
Safe sleep rules for Canada
Canadian safe-sleep guidance is specific, and this hub keeps it front and centre because gear marketing routinely blurs it. The rules from Health Canada and the Canadian Paediatric Society: back to sleep for every sleep until baby rolls both ways on their own; a firm, flat, bare surface in a crib, cradle or bassinet meeting current Canadian regulations; room-sharing without bed-sharing for at least the first six months; no loose bedding, bumpers, positioners or inclined sleepers. Our guides put the rules into practice: SIDS and safe sleep explains the why behind each rule, the crib mattress gap test shows the two-finger check that catches unsafe fit, and when toddlers can have a pillow answers the most common transition question (short version: not before age two, small and firm after).
The gear, honestly ranked
Baby sleep gear is a solved problem pretending to be a complicated one, and Mattress Miracle sells the stuff, so take the candour as it is intended. What matters: a regulation crib, a firm well-fitting mattress, and a wearable sleep sack instead of blankets. The best crib mattress in Canada guide is the flagship: safety standards, firmness testing and honest brand picks, with the organic crib mattress version for parents prioritizing materials. Standard Canadian crib mattresses share one regulated size, with mini-crib and playard exceptions worth checking before you buy, and when to lower the crib mattress covers the milestone everyone misses by a week. Protect the investment with a waterproof crib protector, and for the bigger-kid years ahead, the bunk and kids bed collection at our Brantford showroom is where the fun part starts.
Toddler transitions: crib to bed and beyond
Toddler sleep is transition season: out of the crib, onto a real mattress, into a pillow, and eventually out of the nap. The guides: best toddler mattress in Canada and best kids mattress cover the surface decisions by age and budget, foam vs spring for kids settles the construction question, the children's pillow age guide handles heads and necks, and what size mattress for co-sleeping with a toddler answers the family-bed sizing question honestly. The climbing-out-of-the-crib and when-to-switch guides are in production for this hub. For toddler-proofing the landing, twin bed rails for toddlers covers the guard-rail stage.

Frequently Asked Questions
When do babies sleep through the night?
Later than the internet promises. Many babies manage six-hour stretches somewhere between 4 and 6 months, and research suggests wide normal variation: plenty of healthy one-year-olds still wake. Consistent routines help; developmental readiness decides.
What do Canadian safe-sleep guidelines actually require?
Back to sleep for every sleep, alone in a regulation crib, cradle or bassinet, on a firm flat mattress with no loose bedding, for at least the first six months in the parents' room. Health Canada and the Canadian Paediatric Society publish the full guidance, and every gear guide in this hub follows it.
How long does a sleep regression last?
Typically two to six weeks when routines stay consistent. The four-month regression is the exception: it is a permanent reorganization of sleep cycles, so the goal is adapting to the new architecture rather than waiting it out.

Yes. The showroom at 441 1/2 West Street stocks crib, toddler and kids mattresses plus protectors and bunk beds, and the team checks crib fit before you leave. Call (519) 770-0001 to confirm stock before visiting.
