5 Things That Are Normal in the First Week of Breastfeeding (And a Few Signs Worth Watching For)
By Christy Koraiban, RN BSN LC | Every Baby Feeds
The first week of breastfeeding is hard.
Not because you're doing it wrong. Not because your body isn't capable. But because you're learning something completely new, on no sleep, while recovering from one of the most physically demanding experiences of your life.
And in the middle of all of that, it can feel almost impossible to know what's normal and what isn't.
So let's talk about it.
Here are five things I see constantly in the first week that worry new moms — and that are actually completely expected. Plus a few signs worth paying attention to, because knowing the difference is everything.
1. Nursing Around the Clock Is Normal
If it feels like all you're doing is feeding your baby — you're probably not imagining it.
Nursing 8–12 times in a 24-hour period in the first week is completely within the expected range. Newborns have tiny stomachs, breast milk digests quickly, and frequent feeding is how your body gets the signal to establish, build and maintain supply.
Cluster feeding — where your baby seems to want to nurse constantly for several hours at a stretch — is also normal, particularly in the evenings. It's exhausting. It can feel like something is wrong. It usually isn't.
Frequent feeding in the early weeks is the system working, not failing.
2. Your Milk Isn't "In" Yet — And That's Okay
In the first few days after birth, your body produces colostrum — a thick, concentrated first milk that is small in volume and exactly what your newborn needs.
Colostrum is rich in antibodies, easy to digest, and perfectly calibrated for a brand new gut. Your baby's stomach is about the size of a marble on day one. Colostrum is enough.
Your mature milk will typically come in between days 2 and 5, often accompanied by fullness, engorgement, or a noticeable change in how your baby feeds. Until then, trust the process. Colostrum is doing its job.
3. Some Nipple Soreness Is Common
Tenderness in the first week — especially in the first 30–60 seconds of a latch — is something many breastfeeding mothers experience as their body adjusts.
That initial discomfort that eases once your baby is actively feeding is generally within the range of normal.
What isn't normal: pain that doesn't ease after latch-on, toe-curling discomfort throughout the entire feed, cracking, bleeding, or blistering. Those are signs that something about the latch or positioning needs to change — and that a lactation consultant can help.
Soreness that improves day over day is reassuring. Soreness that is staying the same or getting worse is worth addressing sooner rather than later.
4. Not Being Able to Tell How Much They're Getting Is Part of It
Unlike a bottle, breastfeeding doesn't come with a measuring line. You cannot see what your baby is taking in, and that uncertainty — especially in the early days — can be genuinely unsettling.
Here's what to watch instead: diapers.
After day 5, your baby should have at least 6 wet diapers in a 24-hour period. Dirty diapers will transition from dark meconium to yellow and seedy as your milk comes in. Diaper output is your most accessible and reliable indicator that intake is on track.
You can't measure what's going in — but you can absolutely measure what's coming out.
If the uncertainty is weighing on you, look for a local breastfeeding support group that includes weighted feeds. You can weigh your baby before and after nursing on a calibrated scale so you can see exactly how much they transferred. It's one of the most reassuring things a new breastfeeding mom can experience.
5. Feeling Overwhelmed Is Not a Sign You're Failing
The first week postpartum is hormonally intense in a way that is difficult to fully prepare for.
Your estrogen and progesterone drop dramatically after birth. Your prolactin and oxytocin are surging. You're physically recovering, emotionally adjusting, and running on fragmented sleep while learning something that feels like it should be instinctive but often isn't.
Feeling emotional, touched out, uncertain, or just completely overwhelmed in the first week is real and it is common.
It doesn't mean you're not cut out for this. It means you're doing something genuinely hard — and that you deserve support, not just reassurance.
A Few Signs Worth Watching For
Most of what you'll experience in the first week falls within the range of normal. But there are some things that warrant a closer look.
Reach out to your pediatrician or lactation consultant if:
Your baby has fewer than 6 wet diapers a day after day 5
You notice orange or pink tinted residue (urate crystals) in the diaper after the first 48 hours
Your baby is consistently difficult to wake for feeds or falls asleep within minutes of latching
Your baby hasn't returned to birth weight by two weeks
Pain during feeding is not improving or is getting worse
You have a feeling something is off
That last one matters more than people realize. You know your baby. If something doesn't feel right, that instinct deserves to be taken seriously.
You Don't Have to Figure This Out Alone
The first week is a lot. And while most of what you're experiencing is completely normal, navigating it without support is harder than it needs to be.
If you're unsure whether what you're experiencing is within the expected range, if feeding is painful, or if your baby isn't gaining weight the way they should — reach out. Early support is almost always easier than waiting to see if things resolve on their own.
I work with families throughout North County San Diego and virtually to help breastfeeding get off to the right start — and to troubleshoot when it doesn't go as planned.
If you're not ready to book a one-on-one visit, our free weekly Mother Circle support group is a wonderful place to start. We do weighted feeds at every gathering — so you can get a real answer to that "is my baby getting enough?" question in a warm, supportive setting surrounded by other moms who get it. No appointment needed.
Because the first week is hard for almost everyone. But it doesn't have to stay that way. 💛
