What’s Actually Happening to Your Nipples: The First Breast Changes of Pregnancy.
This little corner of the internet, talking about what the f%$^ is actually happening to your boobs, i.e. the real breast changes during pregnancy and postpartum nobody prepares you for, needs to be talked about more. I’m talking the real, raw, oftentimes shocking symptoms and experiences we have, so they can become normalized, and not just “another experience of pregnancy.” No, I’m over that.
Because here’s the thing nobody puts in the “what to expect” pamphlet at your OB’s office: your breasts go through massive changes during pregnancy and postpartum, almost more than any other part of your body, and the pamphlet’s entire call out is the word “tenderness.” That’s it. Meanwhile you’re in the shower at 34 weeks finding something protruding out of your nipple that is crusty dusty wondering “hum.. that’s weird. Is that normal?”
I envision this blog as a conversation between two friends. Picture this: we’re out having a cocktail (or mocktail), and we’re really getting into the lived experience of what’s going on with our breasts, and we’re about to cover a wide range of these experiences. Cheers.
What’s Actually Happening to Your Nipples Before Baby Even Arrives
Let’s start here, because the changes start way earlier than anyone tells you.
Colostrum shows up first, and it’s not liquid. Somewhere in the third trimester, you might notice something flaky sitting on top of your nipple, almost like a scab, that picks off easily. I expected a thick, gooey substance when people talk colostrum. And yes, that’s true, but before you’re like 37+ weeks, typically you’re gonna find crispy, flakey particles protruding out of your nipples. To which you can physically pick out, which I don’t recommend. However, if it’s bothering you, coconut oil or a lanolin balm keeps things softer.
Your nipples get darker. Not random, strictly functional. Newborns can barely see. Everything is blurry shapes for weeks. The darker areola works like a visual target so your baby can find the food source when nothing else in the room is in focus for them yet.
Your nipples get bigger too. Same visual-target logic, and mine nearly doubled with my first pregnancy. Which is probably one of my least favorite parts of my breasts changing. Loved them getting bigger, perkier and fuller, didn’t love the aerola taking up serious geographic space. Your nipples don’t get longer (you have that to look forward to AFTER nursring.. yayy), but the areola’s “footprint” gets larger.
Then the veins show up. Starting first trimester, building through third, blue veins start mapping across your chest like the A/C/E subway line. (That’s a NYC reference, IYKYK) Here’s the actual reason: your blood volume increases by roughly 40 to 45% during pregnancy. That extra blood has to go somewhere, and your breasts, actively growing and prepping for milk production, get a large share of it. More blood means the veins dilate and push closer to the surface, which is why you’re suddenly seeing a map you never noticed before.
I promise you all of this is completely normal. However, if there are things that feel off (like oozy, green or bizarre colors leaking from your nipples, ya.. no, not normal go see your OB).
The Letdown Nobody Prepares You For – But I’m Going To!
If you read anything in this blog to prepare for breastfeeding, read THIS! 👇👇👇
Fast forward to after your baby arrives. What I’m about to tell you was the most shocking experience, something that wasn’t remotely discussed or prepared for. And I’m excited that I get to share it with you.
If you’ve never breastfed before, you may have heard of the term “a letdown” This is your body physically pushing milk out of your nipple, usually triggered by your baby’s suckling. For me, I pictured a steady stream, like a faucet or hose where milk continually flowed out until your breast was empty.
Noooooooooooope.
This is in fact not how breastfeeding works! It’s more of a gush, then a pause, then another gush, and you can get multiple letdowns in a single feeding. Here’s the detail that broke my brain the first time: whichever side your baby is nursing on, the other side lets down too. Both sides, every time. Double trouble, 2 for 1. (The non-baby breast let down is how I personally collected a 200oz freezer stash. Passively.) I wrote a blog on Boon Trove Milk Collector Review: The Best Baby Shower Gift for Nursing Moms → which is the product I used to do so!
The sensation of a letdown itself: not painful exactly, but a very specific feeling. Closest comparison I’ve got is the pins-and-needles buzz when your arm falls asleep, mixed with a light static shock. Sort of like licking batteries. (anyone?)
And at the exact same time, your body releases oxytocin, which for me turned into this legitimately euphoric head rush. So you’re feeling something strange and something calming in the same ten seconds, which sums up breastfeeding pretty well overall.
(I do want to mention that not everyone experiences this. Some women actually have an opposite effect, and it’s called D-MER [Dysphoric Milk Ejection Reflex]. You might experience fleeting feelings of sadness, anxiety, or irritability. It’s driven by an abnormal drop in dopamine during milk letdown, and I guess it’s ‘normal’, but I’m not a medical expert so if you are experiencing this, might be worth a call to a Lactation Consultant or a call to the OB to make sure it’s not PPD.)
And breastfeeding itself is hard. For me, I had to FIGHT for it. I can honestly say it’s the hardest thing I’e ever done in my life. I wanted to give up, it’s a physical and mental battle. You and your baby are both learning a brand new skill in real time, with zero practice runs. My first week, my nipples were bruised, cracked, and bleeding. Please don’t be scared of it, you’re going to do great! I didn’t properly prepare with all the tools in the tool belt, which I will have on hand for this next baby.
Here’s what actually helped me in my breastfeeding journey, because I’m not going to tell you it gets better and leave you there:
Silverettes:
- I was the biggest skeptic. But wow was I desperate. These are sterling silver nipple covers, recommended by my lactation consultant, worn between feedings. If you buy one item to help your sore nipples. these are it. Skip these and go in with nothing, you’re likely looking at weeks of cracking and painful nipps instead of days. That was the difference for me personally.
Lanolin or coconut oil
- Applied first, Silverette on top. My routine for the first two to three weeks postpartum, anytime I wasn’t actively feeding.
Nipple shields:
- The hospital has them. Not my favorite personally, but a lot of moms swear by them, so don’t rule them out and they’re worth a try if you’re struggling to get baby to latch.
My Best Pregnancy Hack – Buy Nursing Bras When You’re Pregnant!
I’m also going to break down what I spent on nursing bras with my first, which felt like I had enough where I never ran out, but also not too many that my dresser drawers didn’t want to close.
Here’s why it’s my #1 pregnancy hack: your current bras will stop fitting when you get pregnant, no matter how far along you are. So, I bought up nursing bras before I was even nursing, since they flex through the rest of pregnancy and keep working postpartum. I really felt like I optimized my timeline and spending here.
So, here’s how I look at nursing bras. I split them into three categories.
1. Bulk sleep bras from Amazon:
Two four-packs, for the nights when milk is spilling everywhere and you want a fresh one every night: $89.
2. Everyday nursing bras, three Skims:
Which clip open for feeding and still hold real shape: $114.
3. One going-out in public bra, MomCozy Cool Fit:
For the days I actually left the house and wanted to look like a person: $49.
All in: $249, before baby ever arrived.
If you’re my best friend (since we’re out to drinks, and yapping about all of this), asking for my solicited advice on which one to buy, I’m telling you to get all three. Not just one, because they each solve a different problem. I’m testing a wider lineup with baby number two right now, and I’ve got a full nursing bra breakdown coming once I’ve actually lived in each one long enough to give you a real verdict. But I’ve collected about 10 more (and now my drawers are in fact having a hard time closing), but I have already found a few more that I’m loving. Here’s the sneak peak.
- Momcozy Cotton Bra: Super soft and flexible. Sometimes you just need a good ol’ cotton bra.
- Bodily Bra: Expect 0 support, like none. But the softest of all the material. Feels sooooo good.
- A few nursing tanks. I bought these from Nordstrom, but they’re H&M.
The Final Takeaway
That’s the real list of breast changes during pregnancy and postpartum, crusty colostrum, doubling in size, a vein map you didn’t ask for… All of it is normal. I hope this helps you as you’re navigating through your changing body and breasts. It’s such a beautiful journey, and while I am sharing all of this out of experience, everyone has their own preferences and experiences.
