Baby Growth Spurts: Signs and Timelines

Baby Growth Spurts: Signs and Timelines

It seems like it was just days ago when you put the same onesie on your little one – only to discover that now it is too small for them. Your eyes are not deceiving you, and the dryer did not shrink your baby’s onesie

Your newborn has had a growth spurt

Growth Spurt Timeline

Babies already grow at an amazing rate. By the end of their first year, your baby’s weight will have tripled and, and they will have added about ten inches to their height. 

Their growth rate is usually steady, but there are certain periods during your little one’s first year where this physical growth seems to occur at a rapid pace. This is called a growth spurt

These spurts last a few days and sometimes can last as long as a week in some cases. During your baby’s first year of life, they will experience around five growth spurts around these different times:

  • Seven to ten days after birth
  • Between three and six weeks
  • Three months
  • Six months
  • Nine months

Of course, every baby is different, and this is a rough estimate of your baby’s growth pattern. Some babies may experience growth spurts early, and some later. You may not even notice they’ve had an infant growth spurt until you see that their clothes are a little too snug.

There are some less obvious signs that your baby may exhibit when they are experiencing a growth spurt. If you can rule out teething or that your baby is sick, it is most likely a newborn growth spurt, especially if they are within the age ranges listed above.

Signs of a Growth Spurt

It may seem like as soon as you have a solid and consistent routine down to a science with your little one, something throws it off course. Growth spurts can be a culprit, as your baby is experiencing a period of rapid growth, and their body needs extra sustenance and rest to keep up. 

Hungrier Than Usual

Your baby may be showing signs of being extra hungry. They may still show signs of hunger after they finish their bottle or stay nursing longer than they usually do. You may notice that they wake up more often to feed during the night. 

As your baby grows, their tummies are also growing and can hold more milk or formula. If your baby is falling asleep while feeding, they may not be getting enough to eat at that time and will then wake up later when their tummy is empty. 

This is a sure sign that their body needs more nutrition to keep up with the growth they are experiencing.

Sleeping More Often

When it comes to sleeping, two scenarios may occur. Your baby may need more rest or a longer sleep, and you see that they are taking longer naps than usual. On the flip side, your baby may wake up more often during the night and get less sleep due to being hungry. 

Many parents may see periods of sleep regression during this time, where the baby wakes up more than usual during the duration of the night.

Increased Fussiness

An increase in fussiness is also a sign of a growth spurt. Your baby may be hungry, sleepy, or both and will show their frustration by being fussy. 

One big question parents may have about their baby’s developmental leap, is it painful? 

Your baby seems hungrier and fussier than normal. The first thought that parents may have is that their child may be uncomfortable. This isn’t the case. 

Your baby’s little body is changing, but your child’s emotional reaction is due to the change in eating and sleeping needs their body is having, not one of being in discomfort.

What Can Parents Do?

You can do several things if you recognize that your baby is experiencing a growth spurt. The first is to have patience with yourself and your baby’s needs

Growth spurts are a part of the growing-up process, and these spurts won’t last for long. Know that you’ll likely be back to your routine in a few days. It can feel like things will never be the same during the spurt! 

Here are some tips that can make things a little easier for you and your baby.

Feed On Demand

Feed your baby when they are hungry. Opening and closing their mouths, sucking on their thumb or fists, and restlessness are all signs of hunger. Your baby may be ready for feeding more than usual, this is completely normal. 

Don’t Overfeed

Just as important, you don’t want to overfeed your baby. They may need a top-off to get them through until their next feeding as scheduled. If your baby is spitting up or turning their head away from the bottle or breast, that means that they have had enough. 

Overfeeding can cause tummy troubles, and your baby may become even more fussy.

Give Extra Love

With your baby being extra fussy, you’ll need to comfort your baby a little more. Sometimes they just want to be rocked and loved by their parents as their bodies go through big changes. 

Go Easy On Yourself

Give yourself a break! With all the extra feedings, for both breastfed or formula-fed babies, and more wake-ups in the middle of the night, you may find yourself exhausted! Ask for help if you need some extra rest, and don’t worry if the house is a little messy. Your baby depends on you for everything, and this may mean more time solely devoted to your baby.

Monitor Their Signs

Pay attention to their signs. If your baby is super fussy, they may be experiencing more than a growth spurt. Pay attention to their temperature to watch for fever, and watch the amount of dirty diapers. If anything seems off, consult your child’s pediatrician.

Stick to the Routine!

Sometimes extra sleep and food will not do the trick of calming your baby during this period of intense growth in your baby’s progress. Sometimes they just need the stability of your parenting and the routine that they are used to. 

Babies change so rapidly, so keeping a consistent routine helps to keep them grounded and calm. If your baby is experiencing a growth spurt, try to stick to your normal routine as much as possible to give them extra support. If you need to add in an extra feeding or let them nap a little bit longer for some quiet time, definitely give your baby what they need, and hop right back on their schedule.

Keep Up Your Bedtime Routine

One of the most important routines you can keep consistent for your baby is the bedtime routine. Even if you both become thrown off your normal schedule, keeping the bedtime routine as normal as possible helps young babies know that this is the time where we can wind down and get ready to sleep. They also get to spend time with you, and at times, babies just need some tender, loving care to help them feel better.

Make It Simple

Your bedtime routine doesn’t have to be an elaborate circus, usually keeping it as simple as possible is the best. You can start with feeding, then a bath, follow up with a bedtime story, then hugs and cuddles as your baby gets sleepy. 

Even if your baby is experiencing a growth spurt, a full tummy, clean pajamas, and cuddles with their loved one will be sure to help wipe out any fussiness that may still be lingering from the day.

Use The Best Products

One important consideration is the products you implement into your baby’s bedtime routine. Every parent wants to use the best products for their children.
