How to Relieve Constipation in Newborn Babies Quickly

Dear Sarah from six months ago,

It's 3:14 AM on a Tuesday. You're sitting on the edge of the guest bed wearing that awful, bleach-stained grey hoodie from college, holding your sister's four-week-old son, Liam. She's in the hospital recovering from emergency gallbladder surgery, and you graciously offered to take the baby. You have two kids of your own, Leo and Maya, who are 4 and 7 now. You thought you had this in the bag. You're practically a parenting journalist, for god's sake!

But right now, you're clutching a lukewarm mug of coffee from yesterday and frantically typing "constipated babie" into your phone with one numb thumb because Liam's face is the color of a bruised tomato and he hasn't pooped since Sunday. Your husband, Dave, just woke up, looked over your shoulder at the glowing screen, and mumbled, "Did you spell that babi? Like... pastrami?" before rolling over and going back to sleep. Completely useless.

Anyway, the point is, I'm writing this to you because I know exactly how panicked you feel right now trying to figure out the fastest way to unblock a tiny, screaming human. When newborn babies are in pain, or even just look like they're in pain, our rational brains just completely shut down and we turn into desperate internet sleuths.

The great poop panic

thing is I completely forgot about babies since Leo and Maya were tiny: they're so, so loud when they poop. I seriously thought Liam was dying. He was grunting, pulling his legs up, his little fists clenched, sounding like a tiny, angry goat trying to push a boulder up a hill. I was ready to drive him to the emergency room in my pajamas.

But my doctor, Dr. Miller—who I literally texted at 4 AM, bless her soul—told me it's usually not actually constipation at all. It's this thing called infant dyschezia, which is just a fancy medical word for "your baby hasn't figured out how their butt works yet."

Think about it. They're lying flat on their backs, which is a terrible angle for gravity, and they don't know how to relax their pelvic floor while simultaneously pushing with their abdominal muscles. It's like trying to squeeze out a mouthful of water while keeping your lips superglued shut. So they strain and scream and turn purple, but if the poop comes out soft and mushy eventually, they aren't constipated at all. True constipation is when the poop looks like hard little dry pebbles. If it's peanut butter or mustard consistency, you're totally in the clear.

When Liam finally did poop the next morning, it wasn't hard pebbles. Oh god, no. It was a biblical, up-the-back blowout. Thank everything holy I had dressed him in the Organic Cotton Baby Bodysuit from Kianao. I'm absolutely obsessed with this onesie because it has those envelope shoulders. When a baby is covered in toxic waste up to their armpits, you do NOT want to pull that garment over their head. You just pull it straight down over their body. It's made of this super soft organic cotton that actually stretches without stretching out, which is a miracle when you're trying to wrestle a slippery, poop-covered infant.

Movement tricks that actually work

Okay, but what if they are genuinely blocked up and passing hard little pellets? You want to fix it fast. I get it. Just don't go trying to force a bunch of rigid routines on them.

When I was desperately trying to help Liam, I laid him on the floor and started doing those little bicycle legs, just gently pushing his knees up to his chest while singing some weird made-up song about poop, which seriously gets things moving down there, unlike the tummy massage which I always mess up because I forget which way is clockwise when I'm sleep-deprived and end up just kind of uselessly rubbing his stomach while he cries.

Here's what honestly helps speed things along without totally overwhelming them:

• The Tour de France: That's what Dave calls the bicycle legs. You just lay them down and gently pedal their little legs back and forth. It squishes their tummy just enough to release trapped gas and physically push things through the plumbing.
• The deep squat: Hold them with their back against your chest, supporting their thighs so their knees are tucked way up high. Gravity plus the squatting position straightens out their rectum so the poop has a clear exit strategy.
• A really warm bath: I'm not talking about a lukewarm sponge bath. Get them in a nice, warm tub. The warm water just forces their little tense pelvic muscles to finally relax, and honestly, be prepared to catch a turd with a baby washcloth because it works almost too well.

While I was doing the frantic leg-bicycling routine, I had Liam lying under my sister's Rainbow Play Gym Wooden Set. I'll be completely honest with you—it's a gorgeous piece of baby gear, totally aesthetic for a minimalist nursery, but when Maya had a similar wooden gym, she absolutely hated it. She used to just glare at the wooden shapes like they had deeply offended her. But Liam? Liam seriously seemed soothed by it. He liked batting at the little wooden rings while I aggressively cycled his legs. My sister also owns the Panda Play Gym Set, which has this tiny crocheted panda that's undeniably adorable, but when a baby is backed up and furious, any wooden distraction works to stop them from focusing entirely on their own gas pains.

If you're stocking up for the inevitable blowout aftermath—because trust me, once you unblock them, the floodgates open—you should definitely check out Kianao's organic baby clothing collection, because you're going to need way more clean backup outfits than you think.

The thermometer trick is a terrible idea

I really need you to listen to me on this next part, because late-night mom forums are full of absolute garbage advice.

Someone on a Facebook group—I think her name was like, Crystal or something—swore up and down that if your baby is constipated, you should just put a glob of Vaseline on a rectal thermometer and stick it up their butt to "stimulate" them. Oh god. Please don't do this. I brought it up to Dr. Miller and she practically yelled at me through the phone. She said sticking foreign objects up there when a baby is tense and clenching can cause little micro-tears in their rectum, which hurts like hell and makes them even MORE terrified to poop.

Plus, if you get in the habit of doing it, their body gets lazy and they literally forget how to initiate a bowel movement without a piece of plastic triggering it. It's a whole thing. Just don't.

Dr. Miller also mentioned that if he was older than a month I could maybe try a single ounce of pear juice, but he was barely four weeks old, so I just ignored that completely.

Put down the phone and just look at your kid

We overcomplicate everything. I spent two hours that night reading complex scientific studies about how the whey-to-casein ratio in formula affects gut transit times. Like I'm some kind of gastroenterologist? I guess breastmilk has natural laxatives in it or whatever, and formula is just thicker so it takes longer to pass through the intestines. I don't really know the exact science, but I do know that stressing over it doesn't make the poop come faster.

And for the love of everything, don't give a young infant plain water to "flush them out." It messes up their electrolytes and can be super dangerous. If you're mixing formula, just make sure you're honestly leveling the scoops. Dave used to pack the formula scoops for Leo like he was packing brown sugar for a pie crust, which meant Leo wasn't getting enough water in his bottles, and THAT causes massive constipation.

I was so stressed that night, just sitting there in the dark wiping spit-up off my shoulder with the Organic Cotton Baby Blanket with Squirrel Print. I'm not going to lie, that blanket is so soft I seriously considered stealing it from my sister's house. The little squirrels on it are ridiculous and cute, and it was the only soft thing bringing me any comfort at 3 AM while I waited for a baby to poop.

So, past Sarah: breathe. Stop Googling. Keep pedaling those tiny legs. Make sure the formula is mixed right. And if you need to stock up on seriously soft, blowout-friendly gear before the next explosion happens, grab some organic cotton staples from Kianao right now.

The messy questions you probably still have

Why is my newborn's face turning purple when they push?

Because they're basically doing a crunch while holding their breath! It's that dyschezia thing. They're clenching their stomach muscles but forgetting to relax their butt, so all that blood rushes to their face. As long as they aren't crying in agony for hours and the poop is eventually soft, the purple face is totally normal, even though it looks absolutely terrifying.

How long is too long to go without a dirty diaper?

It's wild, but breastfed babies can sometimes go a whole week without pooping because breastmilk is basically the perfect food and leaves very little waste behind. Formula-fed babies usually go every day or two, but can stretch to four or five days. My rule is: if their belly is soft, they're eating normally, and they're passing gas, they're usually fine. If their belly is hard as a rock or they're vomiting green stuff, call the doctor immediately.

Wait, can I just give them prune juice?

If they're a brand new, fresh-out-of-the-oven newborn? No. Under one month, stick to breastmilk or properly mixed formula. Once they hit a few months old, my doctor said a tiny bit of 100% fruit juice like prune, pear, or apple (the "P" fruits... wait, apple doesn't start with P, whatever) is okay because the sugar pulls water into their bowels. But always check with your own doctor first, because every kid's gut is different.

Is the formula I'm using making my baby backed up?

Maybe? Some babies are super sensitive to the iron in certain formulas, or the protein breaks down weirdly in their tummy. But before you go panic-buying six different brands of expensive European formula, check how you're mixing it. Putting the powder in before the water, or packing the scoops too tight, means they aren't getting enough hydration. Fix the water ratio first.

Can I use a glycerin suppository if nothing else works?

I wouldn't touch those without a doctor explicitly telling me to. I know they sell them at the drugstore right next to the diaper cream, but sticking anything up there can mess with their natural reflexes. Let the doctor make that call. Stick to warm baths and bicycle legs until the professionals tell you otherwise.
