Everything You Need To Know About Second Night Syndrome

No, it’s not just you—baby is definitely doing a complete 180 from their first day of life. In fact, almost all newborns go through it too. This is what experts call the “second night syndrome”. It’s a completely normal and common milestone where newborns become more alert, fussy, and demanding during their second day of life—compared to their more “easygoing” first 24 hours.

Being in the immediate haze of postpartum can already be a bit overwhelming for new moms. And now you’re responsible for meeting your newborn’s needs, all while your body is still healing. It can be a lot! Especially when that second night hits.

Something really valuable during this time is advice from experienced moms and baby experts who’re familiar with this so-called second night syndrome. “Babies fuss, there’s no way around it. But there are ways to minimize it,” says Kristin Revere, newborn care specialist and owner of Gold Coast Doulas.

Our team is full of good-to-have information from certified postpartum doulas, newborn care specialists, and experienced moms who’ve helped hundreds of new parents like you tackle this tricky time. And we’re sharing more about this not-so-talked-about phenomenon. Keep reading for a breakdown on what the second night syndrome is, things you might notice, and (of course), some pointers to survive it.

What Is Second Night Syndrome?

Second night syndrome is an entirely normal time when your newborn starts to seem a little fussier and demanding on their second day of life. Think about it like this: Every one of your baby’s needs is met while in the womb. Hungry? Check. Potty? Go right ahead. Snuggles? Mom’s always right there. So, after the love bubble and—quite frankly—exhaustion of birth are over, baby rests for those first 24 hours. And after? This new life starts to set in.

On that second day, baby starts to feel different temperatures, learns how to eat, and has to sleep without the constant 24/7 cuddles. Simply put, your baby realizes they aren’t in the familiar and comfy womb they’ve spent the last nine-ish months floating around in. You need to figure out what works best for your baby, says Kristin. “Learn to really watch and listen. Try to find out what causes the fussiness and react accordingly.” Kristin lists all the ways babies communicate and how you can respond in Supported: Your Guide to Birth and Baby.

Remember, this second night syndrome milestone is 100% normal. Try not to let the word “syndrome” make you spiral. While it can be more difficult during this time, it doesn’t mean there’s anything wrong with baby.

Signs of second night syndrome:

Some common signs of second night syndrome are:

• Cluster feeding. Baby wants to eat even though you just finished your last feeding not too long ago. They also seem to do this in short rotations for hours, sometimes the entire day. Fun fact: This is how baby helps bring your milk in if you’re breastfeeding!
• Short feedings. You’ll typically notice baby start to doze off shortly after starting to eat. Which means no full tummy, and much more cluster feeding.
• No desire to be put down. Baby will be sound asleep in your arms or on your chest, but the moment you put them down, they wake up and start stirring again.
• Extra fussy. Overall, baby might seem much fussier and more vocal than they were in their first 24 hours.

How Long Does Second Night Syndrome Last?

Great news, it doesn’t last forever. Typically, second night syndrome lasts two to seven days. But more often than not, it’s only a few days. Your newborn’s fussiness might continue a bit, but after the second or third night, you’ll start to see these “symptoms” taper off slowly as they become more adjusted to the outside world.

How to Survive Second Night Syndrome

First, know that the extra fussiness is normal. There’s a reason this second night syndrome is happening. And while you can’t totally avoid it, there are some tips to help make this transition easier on you and baby.

Anticipate it

Yes, that might be a whole lot easier said than done, but knowing that the second night syndrome is coming beforehand will catch you less off guard in the moment. Try meeting baby’s needs with peace, and your entire mindshift can change. Sometimes, harder situations are easier when you know what’s coming.

Tons of skin-to-skin

Nope, it doesn’t matter if you’re breastfeeding or bottle feeding, skin-to-skin is another way to keep baby happy during the second day and beyond. Ditch the clothes—you and baby—and spend some quality time daily with baby lying directly on your chest. They’ll love hearing your familiar heartbeat and the comfort of your warm skin.

Recreate the womb

Bringing the comfort baby already knows into their new environment can help ease this harsh transition. Try adjusting the room temperature to a comfy 68 to 72 degrees Fahrenheit. You could also swaddle them, dim the lights, and have a white noise machine going while they sleep.

“No” is a full sentence

Set your hard boundaries and say no to visitors if it feels right to you. If you aren’t feeling up for entertaining guests immediately postpartum, it’s okay. This is especially true during these first few days. Your baby is getting acquainted with their new life and being a little more fussy, and honestly, you might be too—no shame at all.

Assemble your team

Sometimes parents think they have to do it all. But that’s unrealistic if you’re running on empty. If family or friends are nearby, ask for some help around the house. Or to watch baby while you have a moment to yourself.

Soothing a baby can seem impossible when you’re not able to take care of yourself. “Whatever self-care means for you, try to make it a priority—maybe it’s a shower, or a walk around the neighborhood with a friend. Basically, what do you need to feel like you?” says Kristin. Many moms even turn to a postpartum doula, who provides professional newborn help as you navigate your new normal. This can be tremendously helpful.

The bottom line is, if your newborn seems fussier during their second night, you’re most likely experiencing second night syndrome. Thankfully, it’s a completely normal milestone baby is hitting. Most every single parent goes through this, and you’re far from alone if you are too. The good news is, this phase should only last a few days. Hang in there and don’t be afraid to ask for help.
