What Changes Between Months 3 and 4?
You’ve made it out of the newborn stage—and that’s a big deal. Sleep may still feel unpredictable, but your baby is starting to develop real rhythms, making this the perfect time to gently build a routine. Your baby is:
Becoming more alert and engaged
Starting to recognize day vs. night
Moving into more mature sleep cycles
Able to begin sleep training (once approved by your pediatrician!)
Wake windows & total daily sleep
4 Months (Weeks 13–16): 1.5–2 hour wake windows, Total daily sleep: 12–16 hours
5 Months (Weeks 17–19): 2–2.5 hour wake windows, Total daily sleep: 12–15 hours
6 Months (Weeks 20–24): 2–3 hour wake windows, Total daily sleep: 12–14 hours
Night sleep: 9–11 hours (with 1–2 feeds)
Day sleep: 3–5 hours
Naps: 3–4 per day
Here’s a realistic and very flexible schedule:
7:00 AM — Wake + Feed
8:30–9:30 AM — Nap 1
11:30–12:30 PM — Nap 2
2:30–3:30 PM — Nap 3
5:00–5:30 PM — Nap 4
7:00–8:00 PM — Bedtime
1. Wake + Feed (20–30 minutes)
Baby wakes naturally or within a consistent morning window
Full feeding (breast or bottle)
Diaper change before or after feed
Goal: baby is fully fed and content—not snacking
2. Awake Time + Play (45–75 minutes)
Keep stimulation gentle but engaging
Tummy time (5–15 minutes total, broken up as needed)
Talking, singing, eye contact
Play mat, mirrors, or simple toys
Short independent play if tolerated
Watch for early sleep cues (red eyebrows, zoning out, fussiness)
Don’t push full wake windows if baby is tired early
3. Wind-Down (10–15 minutes)
Lower stimulation and create consistency
Dim lights, reduce noise
Sleep sack or swaddle on
Short book, cuddles, or song Gentle rocking if needed
Goal: calm and ready for sleep—not overtired
4. Nap (45–90 minutes)
Place baby down drowsy or asleep
Naps may be inconsistent or short (30–45 minutes is common)
Aim for 4 naps per day with a possible late cat nap
Use dark room and white noise to support longer sleep
Repeat cycle every 1.5–2 hours throughout the day
Bedtime typically falls between 7:00–8:00 PM
Some babies may begin experiencing the 4-month sleep regression during this stage, leading to more frequent night wakings and shorter naps. I personally didn't put too much energy into anticipating regressions because, for my kids, sometimes they happened, and sometimes they didn't. I didn't want to get caught up in the "oh no here it comes" if it wasn't actually going to come. The trick is to stay as consistent with your routine as possible!
The Bedtime Routine I Swear By
If there’s one thing I credit for having great sleepers, it’s ROUTINE, both with naps, and nighttime sleep. I felt comfortable starting a bedtime routine with both of my babies around 13 weeks, and with the blessing from my pediatrician to let them sleep longer stretches. Simple, consistent, and repeated every night— I truly believe it’s what made the biggest difference.
A consistent bedtime routine is one of the most powerful tools for better sleep because it signals to your baby’s brain that sleep is coming. It also helps your baby begin to understand the difference between daytime and nighttime. Over time, the same sequence—bath, pajamas, feed, books—becomes a cue that helps their body start to wind down, making it easier to fall asleep and stay asleep.
Please remember to consult your pediatrician to make sure your baby is able to sleep longer stretches and can stretch out those feedings. Below is a sample schedule, times will vary based on your baby's wake windows!
Simple Baby Bedtime Routine
1. 6:30 PM Bath (10–15 minutes)
Warm bath to signal bedtime transition
Keep lights soft and environment calm
Gentle wash and minimal stimulation
2. 6:45 PM Pajamas + Sleep Sack
Lotion or quick massage if desired
Diaper change
Pajamas on followed by sleep sack or swaddle
Keep interaction calm and predictable
3. 6:50 PM Feed (20 minutes)
Full feeding (breast or bottle)
Quiet, dim environment
Avoid stimulation
Goal: baby is full and relaxed before sleep
4. 7:10 PM Books + Connection (10 minutes)
Read a short book or two
Gentle talking or singing
Cuddles and connection time
Keep this consistent each night
5. 7:20 PM Into Crib
Place baby down drowsy but awake if possible
Turn on white noise
Lights fully off
Goal: consistent, calm transition to independent sleep.
OPTIONAL --> 10 PM Dream Feed.
An optional dream feed around 10 PM can be a helpful way to extend your baby’s first stretch of nighttime sleep. I did this with both bottle fed baby (my first) and breast fed baby (my second). This is a quiet, low-stimulation feed done while your baby is still mostly asleep—often helping them sleep longer without fully waking.
Time It Right, Aim for 2–3 hours after baby’s bedtime (10:00–11:00 PM)
Keep the Environment calm, keep lights off or very dim, no talking or stimulation
Gently Lift baby slowly from crib, keep them mostly asleep or very drowsy.
Feed without fully waking by offering breast or bottle slowly. Baby may latch/feed while still sleepy and that’s exactly what you want—don’t try to fully wake them.
Burp gently if needed, keep movements slow and minimal.
Place baby back in crib while still sleepy.
Important Notes Not all babies respond to dream feeds—if it causes more wake-ups, you can skip it It’s a temporary tool, not a long-term requirement! If it works, it can help extend your baby’s first stretch of nighttime sleep If it doesn’t, your baby may naturally consolidate sleep without it.
