Sleep answers.
The 30+ questions parents actually ask about baby and toddler sleep — answered in 2–3 sentences each, then linked to the full guide. Written by a certified pediatric sleep consultant.
Ages & readiness
At what age can you sleep train a baby?
Formal sleep training is developmentally appropriate from 4 months, once sleep cycles have matured and weight/medical clearance are in place. Before 4 months, focus on foundations — full daytime feeds, age-appropriate wake windows (45–90 minutes), and a dark sleep environment.
Infant sleep training (4–12 months)How much sleep does a newborn need?
Newborns (0–3 months) need 14–17 hours of sleep per 24 hours, per the AAP. Sleep is fragmented into 2–4 hour stretches around feeds. Consolidated night sleep begins developing around 3–4 months.
Newborn sleep foundationsHow much sleep does a toddler need?
Toddlers 1–3 years need 11–14 hours per 24 hours (AAP) — typically a 10–12 hour night plus one 1–2 hour nap.
Toddler sleep solutionsWhen do babies drop to one nap?
The 2-to-1 nap transition typically happens between 13 and 18 months, most often around 15 months. Signs of readiness: refusing one nap for 5+ days, or bedtime drifting past 8 p.m.
When should we move from crib to bed?
Closer to age 3 is ideal for most children. Move earlier only for safety (climbing) or a new sibling arriving. Once the move happens, the plan is boundaries plus a consistent response to getting out.
Is it too late to sleep train a 2-year-old?
No — sleep training works at any age. Toddlers often respond fast because they can understand the plan. Expect 5–14 nights of testing followed by durable change.
Methods
What's the difference between gentle sleep training and cry it out?
Gentle methods (chair, fading, pick-up-put-down) keep a parent in the room and spread lower-intensity crying across 2–4 weeks. Cry it out (extinction) removes the parent and concentrates higher-intensity crying into 3–5 nights. Peer-reviewed research shows equivalent outcomes on attachment, cortisol, and emotional development.
Full comparisonIs cry it out harmful to babies?
The largest study we have — Gradisar et al. in Pediatrics (2016) with a 5-year follow-up — found no differences in attachment, cortisol, or emotional development between extinction, fading, and controls. The AAP considers extinction-based methods safe for healthy babies over 4–6 months.
Which sleep training method works fastest?
Extinction (full cry it out) typically resolves in 3–5 nights. Ferber (graduated) takes 3–7 nights. Gentle methods (chair, fading) take 2–4 weeks. Speed comes with more crying up front; slower methods spread the crying out.
Methods comparedDoes the Ferber method still work?
Yes. Graduated extinction has one of the strongest evidence bases in pediatric sleep. Most babies over 5 months consolidate nights within 3–7 days when the check-in intervals are followed consistently.
Common problems
Why does my baby wake every 45 minutes at nap?
A 45-minute nap ends at one sleep cycle. Babies who haven't learned to link cycles wake fully instead of returning to sleep. The fix is teaching independent sleep-onset at nap start plus adjusting the wake window before the nap.
Why is my child waking at 5 a.m.?
Early rising has four causes: bedtime too late (overtired), nap too long or too late, too much light or noise in the room, or a wake window mismatch. Fix in that order and hold each change for 5–7 nights.
5 a.m. fix frameworkWhat is the 4-month sleep regression?
A permanent neurological change, not a phase. Sleep cycles restructure to be more adult-like around 3–5 months, which is why sleep worsens. It doesn't 'pass' — the sleep architecture is new, and formal sleep training becomes appropriate.
4-month regression guideWhat is the 8-month sleep regression?
A combination of separation anxiety, new mobility (crawling, pulling up), and often a nap transition — all hitting at once. It's real but temporary. Hold the routine, adjust the schedule, and it resolves in 1–3 weeks.
8-month regression guideWhat is the 18-month sleep regression?
Bedtime resistance and testing limits driven by developmental leaps in autonomy and language. Hold the routine, keep the response boring, and don't add new sleep associations. Resolves in 1–2 weeks with consistency.
18-month regression guideWhy does my toddler fight bedtime?
Usually one of three things: a too-flexible routine, a bedtime misaligned with biology, or the child having too much control over the sequence. A tight 20–30 minute routine plus a fixed bedtime with a few small choices built in usually ends the negotiation in a week.
How do I stop my toddler from coming into my room at night?
Walk them back calmly, briefly, without conversation — every time. Most toddlers test hard for 3–5 nights and stop when the response stays boring. OK-to-wake clocks with a clear 'stay in bed until it turns green' rule speed this up.
Wake windows & schedules
What are wake windows?
The awake time between sleep periods. Age-appropriate wake windows prevent both under- and overtiredness — the two most common causes of sleep problems. Newborns: 45–90 minutes. 6 months: ~2.5 hours. 12 months: ~3.5 hours. 2 years: ~5–6 hours.
Full wake windows chartHow long should a bedtime routine be?
20–30 minutes is ideal for ages 1+. Longer invites stalling; shorter doesn't give a child time to wind down. Same sequence every night — predictability is what makes a routine work.
Is a 6 p.m. bedtime too early?
Not for babies and toddlers. Age-appropriate bedtime is 6–7:30 p.m. for most children under 3. Bedtimes past 8 p.m. usually cause overtired wakings and early rising.
Working with a consultant
What does a pediatric sleep consultant do?
Builds a custom sleep plan for your child, then coaches you through running it. The plan covers schedule, environment, feeds, and the specific bedtime/night-waking response. Daily messaging support during the training window keeps you from quitting on night 4.
Packages & pricingHow much does a baby sleep consultant cost?
$249 for the plan-only tier. $449 for the newborn package. $649 for full support with two weeks of daily messaging. Every engagement starts with a free 15-minute call.

Yes. Littleu is 100% virtual across the U.S. and Canada. Video call for the strategy, messaging for daily support. Same results as in-home.
What's the difference between a night nurse and a sleep consultant?
A night nurse takes overnight care off your hands right now, typically for the newborn stretch ($350–$600+ per night). A sleep consultant teaches your child to sleep independently, long-term, for a one-time cost. Most families in high-income markets use both, in sequence.
Full comparisonSleep course or 1:1 consultant — which is better?
A course is a fine starter for foundations. A 1:1 consultant is what you need when the general advice isn't fitting your specific child. Consultants build the plan around your kid's temperament and adjust it daily as you run it.
Courses vs consultantHow long does it take to see results?
Real change in 3 to 7 nights. Fully locked in within 2 to 3 weeks. Daily support is why families don't quit on night four.
Safety
Do your methods follow AAP safe sleep guidelines?
Yes. Every plan follows AAP safe sleep guidance — back to sleep, firm flat surface, no loose bedding, room-sharing without bed-sharing for the first 6 months.
Is sleep training safe for babies?
Yes — for medically healthy babies over 4–6 months, per the American Academy of Pediatrics. Multiple longitudinal studies, including 5-year follow-ups, show no negative effects on attachment, emotional development, or the parent-child relationship.
