Oh, the bittersweet reality of baby growth spurts. Here’s WHEN they happen, SIGNS to look for, and HOW to handle them, plus what other natural mamas do.

Oh, the bittersweet reality of baby growth spurts. One day she’s full of gummy smiles, the next day she’s breaking her first tooth. One day she’s exclusively breastfeeding, the next day she’s eating solids like a champ.

While they can be exhausting and disorienting for both baby and parents, mercifully, baby growth spurts are usually short in duration. The key is to know what to expect so you aren’t caught off guard! Here’s what you need to know, so you and baby can handle a growth spurt with relative grace and ease.

When Do Baby Growth Spurts Happen?

In the first year of life, your baby will gain, on average, three times her birth weight and between eight to ten inches in length.

These changes are both steady and intermittent, with leaps in brain and body development packed into days or weeks throughout the first year. These days of rapid growth and development are sometimes preceded by fussiness and disruptions in your baby’s sleeping and eating routines.

In general, baby growth spurts occur around the following times:

  • Day 2: Newborn growth spurts during the first few days—usually night 2—which is more of a “protest” of leaving your womb, rather than an actual growth spurt. It’s a gassy period for newborns, as their gut flora becomes established in anticipation of the end of colostrum and the arrival of mature breast milk.
  • 2-3 weeks
  • 4-6 weeks
  • 3 months
  • 6 months
  • 9 months
  • 12 months

But remember: Babies don’t abide by clocks and calendars, so your personal experience with baby growth spurts might be different from the standard that’s outlined here.

As your little one grows from toddlerhood to childhood and all the way into the teenage years, her growth spurts will continue. They become longer and more spaced out over time, but in many ways, they still follow the pattern of their first infant growth spurts—arriving with temporary bursts of hunger, crankiness, some aches and pains, and the need for more sleep.

How Long Do Growth Spurts Last?

Thankfully, babies fussiness and discomfort is generally short-lived. Baby growth spurts only last about three days. (source)

Recognizing Baby Growth Spurts

Wondering if your baby is in the midst of a growth spurt? Here are some key signs to look out for:

Increased appetite

Your baby wants to nurse more often, sometimes every 20 minutes (so don’t freak out or worry that you have low milk supply)! It might feel like she’s constantly cluster feeding, especially at night. Conversely, she might lose her appetite, but demand a lot of comfort nursing or suckling. After a day or so of being on and off the breast without eating much, she’ll likely make up for her low appetite by eating lots. Since breast milk production is based on a supply and demand cycle, all feedings will help boost your breast milk supply to accommodate your larger baby.


Your baby may be irritable and need some extra comforting and soothing during a growth spurt. She might seem more clingy and in need of close physical contact with her caregivers. Some parents may wonder if their baby is colic or has baby reflux, but then notice that her mood regulates within a few days.

Sleep changes

Your baby is taking extended and frequent naps, but she’s up for more feedings at night—just when you thought she was finally hitting a routine! Studies show that hormones responsible for bone growth are created during sleep, so a few days of increased napping might lead to a measurable difference in size, but it could also disrupt nighttime sleep in the following days.

Personality changes

Your once curious and playful baby does not want to leave your side. She’s more hesitant and fearful of others, which you may interpret as a sign of developmental regression or an attachment issue. (It’s not!)

How to Handle Baby Growth Spurts

Clear your schedule

Because baby will be “high needs,” it’s best to minimize running errands, visiting with friends, or increasing baby’s stimulation. If you can, clear your schedule, stay in your PJs and keep your schedule as simple as possible. For moms who work full time outside of the home, this probably isn’t feasible, but see if you can rearrange meetings or work a more flexible schedule during baby growth spurts.


As your baby craves more closeness, practice more babywearing to get through these tough times. Baby can easily sleep or nurse snuggled close to your body and you can also be hands-free, so you can get some things done around the house. You can both go shirtless during this time, so that you get a nice oxytocin boost from the skin-to-skin contact, helping to boost both of your moods (not to mention mom’s breast milk supply!).

Practice self care

If you’re breastfeeding, be sure you are eating extra nutrient-dense meals and drinking plenty of fluids during baby growth spurts. This is critical, as you’re in a “growth spurt” right along with baby.

Recruit some extra support from family and friends during this crucial time so that you can care of yourself. Don’t hesitate to ask for help with housework, childcare, and meal prep when you need the extra rest. If you work outside the home, see if you can take a day off or work from home during an infant growth spurt to help take some of the pressure off.

Feed on demand

Breastfed babies will nurse more frequently during a growth spurt (a growing baby is a hungry baby!). Follow your baby’s cues for feeding, offering the breast when she shows early signs of hunger. Give more frequent feeds rather than fewer feeds that last longer, so that your milk supply can respond naturally to any increased demand. If your baby goes through a day without an appetite leading up to a growth spurt, try comfort nursing or giving her more skin-to-skin contact with a family member for comfort.

Take care of your breasts (for breastfeeding moms)

Because more frequent nursing (especially for nighttime feeds) can cause a sudden increase in your milk supply, infant growth spurts can sometimes bring on uncomfortable engorgement for nursing moms. If this happens, treat full breasts by nursing or hand expressing. Keep your milk moving, so that you can stay comfortable. Massage your breasts to keep your breast tissue soft (a warm shower or bath might help, too). More frequent feeding can also bring on sore nipples, so wear loose-fitting tops and use lanolin on nipples (where to buy) or use this DIY nipple cream between feeds. (source)

Let go of expectations

Baby growth spurts could challenge the whole family to give up their attachment to certain routines. As sleep and feeding habits temporarily shift, keep an open mind, and remember that this phase won’t last forever.

It may be hard to recognize in the moment, but increased fussiness and hunger is a positive sign that your baby is growing and developing well. Challenge yourself to appreciate these growing pains just as much as the amazing developmental milestones that they bring. On the bright side, a fussy few days usually indicates that you will have some happier, more settled weeks to come as your baby (and the whole family) relaxes into this next stage of development.

Tips for Formula-fed Babies During Growth Spurts

If your child drinks baby formula, you may need to increase the amount of feeds, but do so gradually. Stick to the recommended number of bottles for your baby’s weight, and if you add an extra feeding, do so only for a few days. (If you work outside the home, be sure to leave extra formula with daycare or your childcare provider, just in case.)

Know that if your baby spits up after a feeding, it probably means she’s getting too much formula.

What If It’s Not Baby Growth Spurts?

If you’re noticing these baby growth spurt signs in your child but they persist beyond a few days to a week, it could be an indication that other issues are to blame. Babies can show increased fussiness and clinginess along with disrupted feeding and sleeping routines when they are getting sick or in response to stress.

Has there been changes in the home? Are you particularly stressed? Has there been job, lifestyle, or home disruptions? These could be culprits.

If you think your baby is sick, consult with your pediatrician. In addition to following their advice, you can still comfort a sick or stressed out baby with some of the tips outlined here.

Other Natural Mamas’ Experiences With Growth Spurts

I asked the moms on my Facebook page about their experiences with infant growth spurts. Here are some of their responses:

  • Lots of sleep! Extra long naps during the day and sleeping all the way through the night when normally waking 1-2 times to nurse. Usually last a couple of days. Sage L.
  • My little girl gets CRANKY!!! Meltdowns at the drop of a hat and eats nonstop. Frankly, with all the extra nursing, I usually realize it’s a growth spurt when my boobs ache from matching my production to her appetite. Sarah F.
  • My daughter had growth spurts around 4 months and 6 months. She always stops sleeping as well throughout the night, frequently waking to nurse. She still hasn’t recovered from her recent spurt! Also, she is cranky and can’t be soothed during the day. Tabitha B.
  • All four of mine ate constantly for a few days, didn’t poop for a day or two, then slept for a day. Kendra R.
  • My little one will just nurse and sleep all day long! It happens about once a month, or sometimes a little bit longer, and usually lasts 1-2 days. Kenz C.

  1. My baby is very fussy during that time, and resists naps. I do everything to try to get her to sleep during the day, but it’s quite a task.

  2. I’m disappointed that mama natural recommends using lanolin to sooth sore nipples. It might be from sheep wool, but it undergoes extensive chemical processsing. There are quite a few other completely natural & organic options available, that are very effective & not disruptive to LO. Lanolin should not be ingested by LO & trying to wipe that stuff off before every feeding is not an easy task.

    • Hi there, I do agree with the comment about the lanolin. Why would you use this chemical cream when you can just pop on some of your own colostrum or breastmilk. It’s literally the best thing you can use!!! ? Also, you can use coconut oil. You don’t need to wipe it of before breastfeeding and it’s completely natural.

  3. My son is going through his 3mo growth spurt at 11wks. He is very hungry, fussy, and wants to nap in my arms. He doesn’t want to be laid down or play. He finally pooped a big load after a day without a bowl movement.

    • Thanks, nice info, but you miss the part about Developmental Leaps. Read the book “The Wonder Weeks”, friends. Growth spurts are physical, leaps are neurological when new milestones appear and are tougher. They cam last from 2 days to a month (the 19th week leap) and once you read the book you wouldn’t start stressing when your baby’s schedule is disrupted. Other than that, this article is a great resource. Thanks for advice about how to manage our routine.

  4. Its so neat how every baby is different. My first hit some milestones before my second such as walking. But my second hit others sooner. Sleeping through the night and crawling.
