The First 72 Hours of Breastfeeding: What I Wish Every Parent Knew Before Delivery
If you’re expecting a baby, you’ve probably spent time thinking about labor, your hospital bag, and what life will look like once your little one arrives.
But there’s one part of postpartum that often catches parents by surprise: the first 72 hours of breastfeeding.
These first few days can feel like a whirlwind of emotions, learning, and questions.
Is my baby getting enough milk?
Why are they so sleepy?
Why do they suddenly want to nurse all the time?
When will my milk come in?
How do I know if breastfeeding is going well?
The good news is that many of the things parents worry about during those first three days are completely expected. Knowing what to anticipate before your baby arrives can help you spend less time wondering if you’re doing something wrong—and more time getting to know your baby.
The first day may be quieter than you expect.
During the first 24 hours after birth, many healthy, full-term babies are surprisingly sleepy.
If your baby has just had an exciting journey into the world, they may need time to recover, regulate, and adjust to life outside the womb.
You’ll still want to offer the breast frequently and take advantage of those early feeding cues, but don’t be surprised if your baby needs some gentle encouragement to wake for feedings.
This is also when your body is producing colostrum—a small amount of highly concentrated milk that’s perfectly designed for your newborn’s tiny stomach.
Many parents worry because they can’t see large volumes of milk.
That’s normal.
The amount of colostrum you produce in those early hours is often exactly what your baby needs.
Day two often feels… different.
If you’ve heard parents talk about “the second night,” there’s a reason.
Many babies become much more alert around 24–48 hours after birth and want to nurse frequently.
Very frequently.
This pattern, often called cluster feeding, can leave parents wondering if they have enough milk or if something is wrong.
In many cases, it’s simply normal newborn behavior.
Frequent feeding helps your baby practice breastfeeding while sending important signals to your body to increase milk production.
It can be exhausting, especially if you weren’t expecting it.
But knowing that this stage is common can help you approach it with more confidence instead of fear.
Your milk doesn’t have to “come in” overnight.
One of the biggest misconceptions I hear is that milk should suddenly appear within a day or two.
In reality, your milk transitions gradually.
Colostrum is your baby’s first milk.
Over the next several days, your body begins shifting toward larger volumes of mature milk.
Many parents notice this change somewhere around days 2–5, although every body is different.
You may notice your breasts feeling fuller.
Instead of focusing on how your breasts feel, pay attention to the bigger picture:
- Is your baby feeding frequently?
- Are you hearing or seeing swallowing during feeds?
- Is diaper output increasing as expected?
- Is your baby being monitored by their healthcare team for appropriate weight changes?
Those pieces of information tell us much more than breast fullness alone.
You and your baby are learning together.
It’s easy to expect breastfeeding to feel natural from the very beginning.
Sometimes it does. More often, it’s a skill that both you and your baby are learning together.
You may spend time adjusting positioning, figuring out what a deep latch feels like, recognizing swallowing, or simply learning your baby’s unique feeding cues.
Every feeding is an opportunity for both of you to become a little more familiar with one another.
Know what’s expected—and know when to ask for help.
One of the most valuable things you can do before your baby arrives is learn the difference between expected challenges and signs that deserve additional support.
It’s common to experience:
- A sleepy baby during the first day
- Frequent feeding, especially during the second night
- Colostrum before larger volumes of milk
- Learning and adjusting your latch together
But if you’re experiencing significant pain with every feeding, your baby isn’t waking to feed, diaper output isn’t progressing as expected, you’re concerned about your baby’s weight, or something simply doesn’t feel right, don’t wait to ask for help.
Trust your instincts. You don’t have to figure everything out on your own.
Don’t put too much pressure on yourself.
I think we put a lot of pressure on ourselves during those first few days.
We expect ourselves to recover from birth, learn how to feed a brand-new baby, navigate sleep deprivation, and somehow feel confident doing it all.
That’s a lot.
The first 72 hours aren’t about becoming an expert at breastfeeding. They’re about getting to know your baby. They’re about learning together.
They’re about recognizing what’s expected, understanding when something deserves a closer look, and having someone you trust to help you make sense of it all.
You don’t have to know everything before your baby arrives.
But having a realistic picture of those first few days can help you enter them with a little more confidence—and a lot less overwhelm.
If you’re currently pregnant, a prenatal lactation consultation is one of the best ways to prepare for those first 72 hours. Together, we can talk through what to expect, answer your questions, and create a feeding plan that’s personalized to your goals, your baby, and your family.
