The final stretch — one more week until the fourth trimester closes


One more week. The fourth trimester — that extraordinary, demanding, transformative chapter that began the moment your baby entered the world — is drawing to a close. Week 11 is the penultimate chapter of this guide, and it is a beautiful one. Your baby is playful, communicative, curious, and increasingly capable. The exhausting early weeks feel genuinely far away now.

There is one thing to be aware of as you head into this week: the 3-month growth spurt is approaching. It doesn’t always arrive precisely at Week 11 — some babies feel it a little earlier, some a little later — but it often makes its presence known somewhere in this window. If sleep wobbles or feeding demand surges this week, you’ll know why. It is temporary, it is normal, and it is the last major growth spurt of the newborn period.

 

Sleep in Week 11

Why might sleep feel disrupted again this week?

The approaching 3-month growth spurt can temporarily disrupt the sleep gains of the previous weeks. Increased night waking, shorter naps, and more difficulty settling are all hallmarks of a growth spurt’s effect on sleep. Hold the course. A growth spurt typically lasts 2 to 5 days, and the sleep pattern almost always returns — and often improves — on the other side.

What are awake windows like at 11 weeks?

Awake windows at 11 weeks are typically 75 to 100 minutes — slightly longer than previous weeks as your baby’s capacity to stay alert and engaged continues to grow. Watch for tired cues at the 90-minute mark and begin winding down before baby reaches full overtiredness.

How many naps at 11 weeks?

Most 11-week-old babies are taking 3 to 4 naps per day. The first morning nap is often the longest and most reliable. An early evening catnap is still common and helpful at this age to make it to bedtime without becoming overtired. Don’t be in a rush to drop it — it is doing important work right now.

Quick Tip: If the growth spurt disrupts sleep this week, resist the urge to change your approach. Growth spurt sleep disruption is temporary, and introducing new sleep associations during the disruption can make the return to baseline harder. Stay consistent, lean into responsive care, and let the spurt pass — your routine will return on the other side.

 

Feeding in Week 11

What does feeding look like during the 3-month growth spurt?

The 3-month growth spurt brings another surge in feeding demand — likely the last major one of the newborn period. Your baby may want to nurse or bottle feed more frequently and with more urgency for several days. For breastfeeding parents, this is your body receiving its signal to increase supply for the next phase of your baby’s growth. Feed on demand without restriction during the spurt, prioritize your own nutrition and hydration, and know that the increased demand is temporary and purposeful.

Is distracted feeding still happening?

For many babies, yes — distracted feeding is still very much a feature of Week 11. Most babies begin to improve significantly around weeks 12–14. In the meantime, continue with low-stimulation feeding environments. One thing that may help particularly around Week 11: offering a top-up feed about 20 minutes before the start of the bedtime routine when your baby is calm and alert, so they arrive at the bedtime feed less hungry and more able to feed without distraction.

What is the typical feeding pattern at 11 weeks?

Outside of growth spurt days, most 11-week-old babies are feeding approximately every 3 to 4 hours during the day — a pattern of 4 to 5 daytime feeds is very typical. Many babies are also consolidating to one overnight feed (or none) after a longer first overnight stretch. The feeding day is becoming genuinely manageable and predictable.

Quick Tip: If you are breastfeeding and the 3-month growth spurt feels like your supply has suddenly dropped, it almost certainly hasn’t. The sensation of breasts feeling ‘empty’ or ‘less full’ around 3 months is a sign that your supply has regulated to meet your baby’s exact needs — not that it has decreased. A regulated supply that meets demand is the goal. Trust the diaper output and your baby’s satisfaction after feeds over how your breasts feel.

 

Diaper Changes in Week 11

What’s normal for diapers at 11 weeks?

Wet diaper output remains your most reliable indicator — 6 or more wet diapers per day is your ongoing benchmark. Bowel movements in breastfed babies continue to range widely at this age. During the growth spurt, you may see a temporary increase in stool frequency as feeding demand increases. Formula-fed babies generally maintain a more consistent daily bowel movement pattern throughout.

Is this a good time to review the diaper and skincare routine?

Week 11 is a wonderful time to settle into a sustainable diapering routine that will carry you through the coming months. For most babies at this age, 6 to 8 diaper changes per day is appropriate. Nighttime skin protection with a generous zinc oxide barrier remains important, especially if your baby is doing longer overnight stretches.

Growing out of diapers and clothes — again

The 3-month growth spurt is often accompanied by a very visible physical growth leap — you may notice your baby suddenly looking longer or heavier. Many families find that diapers and clothing they thought would last another few weeks are suddenly too small after a growth spurt. Check fit regularly this week and don’t be surprised if you’re sizing up in both diapers and clothing simultaneously.

Quick Tip: The growth spurt at 3 months often produces the biggest single-week weight gain of the entire newborn period. If you have a baby scale at home or can stop by your pediatrician’s office for a weight check, you may be genuinely amazed at the number — it’s a powerful reminder that all the feeding you’ve done has been building something extraordinary.

 

Baby Behaviors & Development in Week 11

Week 11 is brimming with development. Here is what is happening in that beautifully growing brain and body this week:

Laughing — for real

If the first real laugh didn’t arrive in Week 10, Week 11 is prime territory for it. Many babies produce their first genuine, full belly laugh somewhere in the 10–12 week window — in response to a funny face, a raspberry blown on their tummy, being swung gently in the air, or a particularly exaggerated vocal expression from you. It will likely catch you both by surprise the first time — and you will spend the rest of the day trying to recreate it.

Early consonant sounds

Beyond the vowel sounds and coos of earlier weeks, your baby may begin producing early consonant-like sounds around Week 11 — sounds that contain a hint of “m,” “b,” or “g” at the front. These are not intentional words, but they are the very beginning of the sound-shaping that will eventually produce babbling and then language.

Deliberate hand exploration

Your baby’s hands are becoming one of their primary objects of fascination at Week 11. You may notice them holding their hands in front of their face and studying them intently — opening and closing, watching the fingers move, bringing hands together at the midline. This is the very deliberate process of discovering that those fascinating moving things are actually part of them, and that they can control them.

Stronger, more exploratory tummy time

Tummy time at Week 11 is becoming genuinely enjoyable for many babies. Most can hold a strong head lift at 45 to 90 degrees, many are in the mini push-up position, and some early movers may even be beginning to shift their weight from side to side — a precursor to rolling. Continue building tummy time into every awake period.

Expanding world awareness

Your baby’s awareness of the world beyond the immediate is growing rapidly at Week 11. They may notice things across the room, track a pet moving through the space, or turn toward a sound from several feet away. Their visual range now extends to approximately 18 inches and beyond, and their interest in new environments is noticeably more engaged.


A Note from the TLNC Team

Week 11 is the penultimate chapter — and we want you to take a moment to truly see how far you have come. Eleven weeks ago, you were in the thick of those earliest, hardest days. Today, your baby is laughing, playing, and showing you exactly who they are. Every feed you gave, every night you got up, every moment you showed up even when you were running on nothing — it all built this. Your personalized weekly care report captures your baby’s unique journey through this final stretch — keep reading alongside this guide for the full picture.

The growth spurt will pass, sleep will settle back in, and next week the fourth trimester officially closes. You are going to close it beautifully. We are so proud of you.

Eleven weeks of extraordinary love and effort. One more week and a new chapter opens — one where your baby is no longer a newborn, but a curious, capable, communicative infant who is ready for everything the world has to offer. You brought them here. What a remarkable thing you have done.

With warmth,

Roxanne Stinson & The Tender Luv Nu-Born Care Team
