Is your baby suddenly more ravenous than usual? This could be a sign that they’re experiencing a growth spurt. Learn when growth spurts typically occur and how to identify if your little one is in the middle of one.
Just when you’ve adjusted to a somewhat predictable feeding routine, your baby might suddenly switch gears. You may find your little one eating more frequently and still acting hungry after finishing a meal.
If you’re concerned about whether your baby is getting enough milk, don’t worry. Your seemingly insatiable eater isn’t starving—they’re likely going through a growth spurt. Growth spurts are a natural and exciting part of your baby’s first year, marking their rapid development and progress.

What Are Baby Growth Spurts?
During their first year, babies grow at an extraordinary rate, often in short, intense periods known as growth spurts.
In this time, babies typically triple their birth weight and gain about 10 inches in length. These bursts of growth can feel sudden—one day your baby fits perfectly in their clothes, and the next, they seem to have outgrown everything in their wardrobe!
Before a growth spurt, you might notice gradual weight gain. Afterward, there’s usually a noticeable leap in their size and development.
When Do Babies Have Growth Spurts?
Baby growth spurts can occur at any time during the first year, but they tend to follow certain patterns.
Here are the common times you might notice these spurts:
- 1 to 3 weeks
- 6 to 8 weeks
- 3 months
- 6 months
- 9 months
Remember, these are general guidelines, and your baby’s growth spurts might not align perfectly with these timeframes.
Dr. Micah Resnick, a board-certified pediatrician, notes, “Growth spurts are influenced by genetics, environment, nutrition, sleep, and other factors. Timing can vary widely among babies.”
To track your baby’s growth, your pediatrician will use growth charts from the World Health Organization (WHO) or the Centers for Disease Control and Prevention (CDC). These charts compare your baby’s weight, length, and head circumference to those of other babies their age.
Signs of a Baby Growth Spurt
It’s not always easy to tell whether your baby is experiencing a growth spurt or simply having a hearty appetite. Here are some signs that your baby may be going through one:
- Increased hunger
Your baby may seem to want to eat nonstop—sometimes every hour or even every 30 minutes. Breastfeeding babies stimulate milk production with frequent feedings, while older babies may nurse more and increase their intake of solid foods. - Frequent night wakings
Even if your baby was sleeping in longer stretches, a growth spurt can lead to waking up multiple times at night for extra feedings. Naps may also become shorter. - Increased fussiness
Your baby might be fussier than usual, especially during feedings. They may latch and unlatch repeatedly, frustrated that your milk supply hasn’t yet caught up with their increased appetite.
How Long Do Growth Spurts Last?
While it may feel like your baby will be endlessly hungry, growth spurts are usually short-lived.
Most growth spurts last just a few days. During this time, your baby’s intense hunger and fussiness will gradually subside, and things should return to normal.
“There’s no fixed timeline for growth spurts,” says Dr. Resnick. “Just feed your baby when they’re hungry, and trust that their needs are being met.”
Do Babies Sleep More During Growth Spurts?
Some babies may sleep more during a growth spurt, while others experience more frequent night wakings.
Research suggests that growth spurts can sometimes lead to increased sleep as your baby’s body focuses on development. However, the extra energy demand might also lead to sleep regression, causing them to wake more frequently for feedings.
How to Handle Baby Growth Spurts
Caring for a baby during a growth spurt can be exhausting, especially if you’re already sleep-deprived. Here are some tips to help you manage:
- Stay hydrated and nourished
If you’re breastfeeding, drink plenty of water to support milk production. Eating nutrient-rich meals can also help you maintain your energy. - Accept help when offered
Ask your partner, family, or friends to assist with household tasks, giving you more time to focus on feeding and resting. - Feed on demand
Follow your baby’s hunger cues and offer extra feedings as needed. Breastfeeding frequently helps boost your milk supply to meet their growing needs. - Monitor diapers and weight gain
If your baby is gaining weight steadily and soaking 5–6 diapers daily, they’re likely getting enough to eat. - Give yourself grace
It’s normal to feel overwhelmed during a growth spurt. Take breaks when you can and remind yourself that this phase is temporary.
Will Growth Spurts Affect Breastfeeding?
Breastfeeding during a growth spurt can be challenging, but it’s essential to keep going if possible.
Frequent feedings are your baby’s natural way of increasing your milk supply. While it may feel like you’re constantly nursing, this period will help your body adjust to their new nutritional needs.
If you’re concerned about your milk supply or your baby’s feeding habits, don’t hesitate to reach out to your pediatrician or a lactation consultant for guidance.
What Happens After a Growth Spurt?
Once the growth spurt ends, your baby’s appetite and sleep patterns will typically return to normal—until the next growth spurt, that is!
Each growth spurt is a reminder of how quickly your baby is growing and developing. Celebrate these milestones, even if they come with some sleepless nights and extra feedings.
By staying attentive to your baby’s cues and offering plenty of love and care, you’ll navigate growth spurts like a pro and continue supporting your little one’s incredible journey of growth.
