Baby Sleep Training (4–12 Months).
Certified sleep training for 4–12 months. Regressions, night wakings, nap transitions — fixable with the right plan.
Common challenges
What's happening at this age.
- 4-month regression that never ended.
- 3–5 night wakings. Used to be one clean feed.
- 30-minute naps. Overtired by 10 a.m.
- 2-to-1 nap transition wrecking bedtime.
- Rocking, nursing, bouncing — and it stopped working.
- 5 a.m. wakeups with no way to push them.
The approach
How Jenna works with this stage.
From 4 months on, structured training works fast. Every plan starts with your comfort level. Jenna builds around your line, not hers.
Fall asleep independently. Connect sleep cycles. Consolidate naps. That's the technical part.
The bigger part: nights three and four. When kids test it and parents want to quit. Daily texts are where the gains happen.

Quick answers
Questions parents ask about this age.
When can I start sleep training my baby?
Most babies are developmentally ready for structured sleep training between 4 and 6 months. By this age they can consolidate night sleep and connect sleep cycles. Before 4 months we build foundations; after 4 months we run a real training plan.
Is 4 months too early to sleep train?
No — 4 months is the earliest developmentally appropriate age for structured sleep training and often the easiest window. Sleep cycles have just matured, habits aren't deeply engrained yet, and mobility isn't complicating the crib. Waiting longer usually makes training harder, not easier.
How long does the 4-month sleep regression last?
The 4-month regression is a permanent change in how your baby sleeps, not a phase you wait out. The disruption typically resolves within 2–6 weeks once your baby learns to fall asleep independently. Without a plan, it commonly stretches to 3–6 months of frequent wakings.
Why is my baby waking every hour at night?
Hourly wakings almost always mean your baby needs help falling asleep — feeding, rocking, or bouncing — and can't reconnect sleep cycles independently. Every 45–60 minutes a cycle ends and they wake fully because the sleep condition has changed. Teaching independent sleep-onset resolves it.
What are wake windows for a 6-month-old?
Most 6-month-olds do best on wake windows of 2 to 2.5 hours between naps, with a slightly longer 2.5–3 hour window before bed. Total daily sleep at this age is 13–15 hours across 3 naps and 11 hours overnight.
When do babies drop to 2 naps?
Most babies drop from 3 to 2 naps between 6 and 9 months old. Signs it's time: the third nap is a fight, bedtime keeps drifting later, or the third nap has become impossible to fit in. The transition takes 1–2 weeks to settle.
Can you sleep train while breastfeeding?
Yes. Sleep training and breastfeeding are fully compatible — the plan is built around your feeding setup, not against it. You can keep night feeds, drop them, or wean gradually; the plan adapts to what you want. Nothing about sleep training requires you to stop nursing.
Why is my baby waking up at night after sleeping through?
Common causes are the 8- or 12-month regressions, teething, nap transitions, illness, or an independent sleep skill slipping under a new prop. A plan identifies which one is driving the wakings and fixes the actual cause instead of throwing everything at the wall.
