Welcoming a newborn into your family is one of life’s greatest joys but with many questions and concerns, particularly regarding your baby’s growth and development. One of the most crucial aspects of early development is newborn baby growth spurts. These rapid periods of growth catch parents off guard, leading to sleepless nights, extra feeding sessions, fussiness, and lots of wondering about what’s normal. Newborn baby growth spurts are part of development.
This guide will delve deep into everything you need to know. By the end, you’ll understand your newborn’s body and how to support them through these growth periods.
What Are Newborn Baby Growth Spurts?
A newborn baby growth spurt is a period of accelerated growth in which the body and brain change height, weight, and developmental abilities. During these times, babies grow in weight, length of limbs, and head circumference. Growth spurts are a good indicator your baby is growing as it should, but they can also lead to temporary disruptions in their routine. Understanding the timing and signs of these spurts helps reduce stress for you and your baby.
Why Newborn Baby Growth Spurts Important in Development—Why Do They Happen?
Newborn baby growth spurts are essential in development, helping babies achieve physical and developmental milestones. The baby’s development isn’t limited to physical growth—cognitive and emotional changes also occur. The baby’s cells work overtime during these growth phases, allowing for rapid development of muscle, bone, and organ tissues. The brain also undergoes growth during these periods, contributing to cognitive and motor skills. Developmental milestones trigger these growth spurts.
For instance, a baby might experience a growth spurt right before hitting a significant milestone, such as rolling over or sitting up. This connection between physical growth and skill development highlights the importance of these spurts in the baby’s overall development.
Indeed, newborn baby growth spurts are essential for achieving milestones, such as learning to hold their head up, roll over, and eventually sit and crawl. These spurts help the baby’s brain mature, improving their ability to process the world around them, recognize familiar faces, and respond to stimuli like sound and touch.
Newborn baby growth spurts are a natural part of development, helping babies grow and mature physically and cognitively. Babies become more demanding—feed more frequently, sleep more (or less), and show discomfort or fussiness. While these phases are exhausting for parents, they signify your baby is growing as expected.
When Do Newborn Baby Growth Spurts Happen?
While every baby is unique and experiences growth spurts at different times, there are common patterns when these spurts typically occur. The first year of life is a time of rapid growth, and you may notice growth spurts at specific intervals. Here’s a rough guide to when you expect newborn baby growth spurts:
- 7-10 days: In the first two weeks of life, your baby becomes more alert and recognizes their environment.
- 2-3 weeks: As the baby’s body grows, it results in more frequent feeding and noticeable weight gain.
- 4-6 weeks: A major growth spurt marked by a noticeable change in appetite and sleep patterns.
- 3 months: There’s significant physical growth and developmental leaps.
- 6 months: The half-year point brings a dramatic growth spurt, particularly as babies experiment with solid foods and further develop motor skills.
- 9 months: The last significant growth spurt of the first year when the baby gears up for walking and other physical milestones.
The timing and frequency of growth spurts vary among babies. Genetics, nutrition, and overall health determine when and how often your baby will go through a growth spurt. Breastfed babies, for example, have more frequent growth spurts because they tend to feed more often, especially during rapid growth. Meanwhile, formula-fed babies experience increased feeding on a more predictable schedule.

Signs of Newborn Baby Growth Spurts
1. Increased Hunger and Feeding Frequency
This is a clear sign that your baby is going through a growth spurt. Babies need more calories and nutrients to fuel their rapid growth, so they want to eat more than usual. For breastfeeding mothers, this means your baby wants to nurse every hour or two.
If formula feeding, your baby finishes their bottles faster and requires more formula throughout the day. This increase in appetite is known as “cluster feeding” in breastfeeding babies. Babies seem insatiable during a growth spurt, which is exhausting for parents but it’s important.
For breastfeeding mothers, this frequent feeding helps to increase milk supply to meet the baby’s growing demands. This sudden spike in appetite is your baby’s way of signaling they need more nourishment to support their body’s growth.
How to Support: Feed on Demand
Whether breastfeeding or bottle feeding, respond to your baby’s hunger cues and allow them to eat as much as they need. Babies need more calories to fuel their rapid growth, so their feeding frequency will increase. This ensures your baby gets the nutrients to grow and develop healthily.
For breastfeeding mothers, frequent nursing during a growth spurt stimulates your body to produce more milk. Your baby’s increased demand for milk will naturally boost your supply to meet their needs. If formula feeding, you need to increase the amount you offer in each bottle or feed your baby more often.

2. Changes in Sleep Patterns: More or Less
There’s a shift in your baby’s sleep schedule. Babies sleep more during a spurt, as their bodies need extra rest to support the increased growth. You find your baby taking longer naps or sleeping for extended stretches at night. However, some babies do the opposite and sleep less because they wake up more frequently to eat.
On the other hand, some babies become more restless during growth spurts, waking frequently to feed or showing difficulty settling down for naps. This is challenging for parents, but these sleep disruptions are short-lived. While it might seem contradictory, increased and decreased sleep are normal signs of a growth spurt. What’s important is to pay attention to your baby’s cues and adjust their schedule as needed to accommodate these changes.
How to Support: Stick to Your Baby’s Sleep Cues
Growth spurts cause temporary disruptions in your baby’s sleep, but ensure they get enough rest for their growth and development. Pay attention to your baby’s sleep cues and be flexible with their nap schedule. If your baby seems more tired than usual, allow them to nap longer or sleep earlier in the evening.
Conversely, if your baby wakes up more frequently at night to feed, be patient—this phase won’t last forever. Offer comfort and maintain a calming bedtime routine to soothe your baby back to sleep when they wake up in the middle of the night.
3. Fussiness and Clinginess
Your baby seems more irritable, cries more often, or wants to be held more frequently during a growth spurt. This is frustrating for the baby and parents, but this behavior is temporary. The increase in clinginess is tied to your baby’s emotional and cognitive development. As their brain grows and becomes more aware of their surroundings, they seek out physical closeness from caregivers to feel safe and secure.
How to Support: Feed on Demand–Provide Extra Comfort and Cuddles
Fussiness and clinginess are common during growth spurts, as babies seek more comfort during periods of rapid change. Providing extra physical closeness, whether through holding, rocking, extra cuddles, or babywearing, will soothe your baby and make it feel more secure. Also, offer a pacifier if your baby wants to suck for comfort but is not hungry. Sucking is soothing for babies, and pacifier calms them between feedings.
4. Noticeable Growth in Size and Weight
One of the most exciting signs is weight gain and longer limbs. During these spurts, babies gain weight quickly, and you notice that their clothes feel tighter or shorter than before. Their legs, arms, and bodies lengthen, and their faces appear rounder as they fill out. If you regularly weigh your baby or measure their length, you notice a sudden jump in their measurements following a growth spurt. These physical changes signify that your baby is growing as it should.
How to Support: Take Care of Yourself
Growth spurts can be exhausting for parents, especially when your baby wakes up more frequently at night or demands extra attention during the day. Take care of yourself during these times so you can better support your baby. Try to rest when your baby naps, stay hydrated and eat nutritious meals to keep your energy levels up.
If you’re feeling overwhelmed, don’t hesitate to ask for help from your partner, family, or friends. Growth spurts are a natural part of your baby’s development, but they can be demanding for parents, and it’s okay to seek support when needed.
Growth Spurts and Milestones: What to Expect
Physical Milestones
Growth spurts coincide with the achievement of physical milestones. As your baby’s body grows, so do their abilities to perform physical tasks. For example, expect milestones after a growth spurt. These could be your baby gaining better head control, rolling over, or reaching out to grab toys and objects. These new skills are signs your baby’s muscles and coordination are developing in line with their physical growth.
Cognitive and Emotional Milestones
Growth spurts don’t involve physical changes—they also play in your baby’s cognitive and emotional development. As your baby’s brain grows, they become more aware of their environment and develop cognitive abilities. You notice your baby recognizes familiar faces, smiles at you more often, or alertly responds to sounds.
Emotionally, your baby becomes more attached to you. They seek more comfort from caregivers, especially during times of fussiness. This increased attachment is a normal part of their emotional development as they understand safety and security.
What to Watch For: When to Contact Your Pediatrician
While growth spurts are a normal part of development, monitor your baby’s health and overall well-being during these periods. Some red flags include:
- Refusal to eat: If your baby refuses to eat or has a significant drop in appetite.
- Lack of weight gain: Regular weight checks are important. If your baby isn’t gaining weight or seems to be falling behind on their growth curve, a healthcare provider should assess the situation.
- Fever or illness: If your baby has a fever, rash, or other signs of illness along with changes in behavior, it could be something other than a growth spurt.
