Dictionary of Breastfeeding Mothers: The Language of Motherhood Explained

If you've come here looking for a dictionary of breastfeeding mothers or a small glossary of terms for new mothers, don’t worry. You are not alone. And no, you don’t need a university degree to be a mother… although any help is welcome in this motherhood journey.

So, if you need a mini-guide to understand the language of moms in 2026, we are here to “translate” the most commonly used concepts of that language — which sometimes seems secretive — of modern mothers.

The other day, in consultation, Mari Carmen (42 years old, first pregnancy) looked at me with wide eyes and said:

—Celia, I spent my entire childhood traveling in a car without a car seat while my father smoked Ducados and my mother gave me chocolate bread for an afternoon snack every day, why do I now need to know what a “sleep window” is?

And then I understood what was happening to her.

Mari Carmen had started to inform herself. She had joined pregnant groups, listened to podcasts about motherhood, and even entered forums.

And in less than 48 hours, she had discovered that:

• Breastfeeding is always “on demand.”
• Babies don’t sleep poorly; they go through regressions.
• Tantrums don’t exist; they are evolutionary processes of emotional regulation.
• And if you don’t know what BLW is, it seems your kitchen is stuck in 1992.

But every time she learns a new term, she feels like someone has changed the language of motherhood without warning, again.

So let’s organize this glossary of breastfeeding mothers' terms. With humor, but with rigor.

Baby Sleep: Terms Found in the Dictionary of Breastfeeding Mothers

If child sleep has always been complicated, now it turns out we were doing it “regulinchi” because we didn’t know the theory. That is, we didn’t know its phases or the regressions. Now we have access (almost) to more information than we need.

Mari Carmen, after two afternoons on Instagram, came alarmed:

—Celia, can I calculate the sleep window of my baby who hasn’t been born yet? Should I keep track on an Excel sheet?

We breathed.

The famous sleep window is simply the approximate time a baby can be awake before needing to sleep. If you exceed it, they can become overstimulated. Nothing more.

Then there are sleep regressions or developmental awakenings. Before, you would say “this week they are sleeping terribly.” Now we know there are developmental moments when the brain matures and sleep changes.

Add these terms to your personal glossary:

• Micro-awakenings: brief interruptions of sleep between cycles that can turn into nighttime awakenings.
• Sleep association: when the baby learns to fall asleep after an activity or with an object.
• Sleep ritual: a relaxing routine that prepares the body for sleep.
• White noise: a constant sound that masks other noises.
• Co-sleeping: sleeping with the baby in the family bed.
• Sidecar crib: a crib attached to the parents' bed.
• Bridge naps: transition naps to avoid excessive tiredness.
• Overstimulation: excess sensory stimuli that causes irritability.

When the baby’s rest becomes particularly difficult, understanding how their development works can make a difference. Infant sleep consulting allows for analyzing each family’s specific situation and proposing changes adapted to their reality.

Breastfeeding: From the Most Natural to the Technical Universe

Mari Carmen thought that breastfeeding was just pulling out the breast and that’s it.

Wrong.

After three videos she had seen on Instagram, she already knew more acronyms than in her work life.

—Celia, is this exclusive breastfeeding, mixed, extended, deferred, or streaming?

Let’s break it down.

Exclusive breastfeeding (EBF) means that the baby only takes breast milk. Mixed combines breast milk and formula. Extended means breastfeeding beyond the first year.

Giving breast milk deferred means expressing it with a breast pump or manually and offering it to the baby later.

• Nipple analgesia: using the breast to relieve pain.
• Non-nutritive sucking: the baby sucks without feeding.
• Breastfeeding crisis: periods when the baby demands more breast to increase production.
• Power pumping: an intensive technique to stimulate production.
• Deep latch: when the baby takes a large part of the areola.
• Tongue tie: limitation of tongue movement.
• Nipple-bottle confusion: difficulty latching onto the breast after using a bottle.
• Nipple shields: temporary tools to facilitate latching.
• Relactation: recovering production after having interrupted it.
• Milk bank: expressing and storing breast milk.

And suddenly Mari Carmen feels like she’s at an international conference.

But when explained clearly, everything fits. Information doesn’t complicate; it clarifies. As long as someone translates it.

When doubts arise about latching, milk production, or pain while breastfeeding, having a lactation consultant can help understand what is happening and how to resolve it in a personalized way.

Complementary Feeding: When English Invades the Kitchen

If learning the vocabulary of breastfeeding was complicated, understanding the one specific to complementary feeding is a challenge.

—Celia, I used to eat purees. Now I have to know what BLW, BLISS, and finger food are. Did my mother do it wrong?

No. Your mother did what was known at that time.

BLW (Baby Led Weaning) simply means letting the baby feed themselves starting at 6 months, in pieces appropriate to their age, adapting texture and always with adult supervision.

BLISS (Baby-Led Introduction to Solids), on the other hand, is an improved version of the first and focused on being safer. The mixed method combines both.

Then come terms that generate cold sweat:

• Gag reflex vs choking: the gag reflex is an automatic defense response that constricts the throat to prevent something from passing into the airway. Choking, on the other hand, occurs when food blocks the airway.
• Early allergen introduction: involves introducing potentially allergenic foods around 6 months while maintaining breastfeeding. This helps prevent food allergies.

And this is where the right information makes the difference between panic and security.

It’s not a trend. It’s evolution in scientific evidence.

At this stage, it’s also common for many questions to arise about textures, safety, or food introduction. Complementary feeding is a process that should be approached with clear information so that the baby can eat safely and the family can gain peace of mind.

Parenting and Development: Big Words for Human Processes

Here Mari Carmen was already tired.

—Celia, before kids had tantrums. Now they activate the autonomic nervous system. I need subtitles.

I understand the feeling.

Respectful or conscious parenting is not an elitist label. It’s about trying to educate without violence, focusing on love, empathy, and emotional connection between parents and the child.

We talk about secure attachment, meaning a stable and affectionate bond, where their needs are always met, which will favor their future autonomy.

Another term we love is exterogestation: 9 months inside the mother’s womb and the next 9, well “attached” to it.

During the first months outside the womb, the baby remains extremely dependent. Their mother is usually the one who provides food and also the basic care they need to live.

Now it seems that all babies are high demand, but let’s be clear, all newborns need constant contact with their primary attachment figure. It’s not a whim; it’s a biological need as important as eating.

Terms like:

• Free movement: promotes the child’s motor development, allowing them to explore their environment and try new positions without adult intervention. Floor time, floor time, and more floor time. Avoid the use of walkers and bouncers, except for specific moments.
• Positive discipline: an educational approach based on empathy, love, and mutual respect.
• Co-regulation: a process in which the adult helps calm and manage the emotions of their child.
• Validating emotions: the process of recognizing and accepting emotions (one’s own and/or others).
• Neurodevelopment: the maturation process of the nervous system (motor, cognitive, social skills, etc.).
• Developmental tantrum: usually occurs between 2 and 4 years and is the result of frustration and difficulty managing their own emotions due to immaturity.

These terms are not a passing trend. They are attempts to better understand child development.

Although, yes, I admit that when heard all together they sound like the syllabus of a postgraduate course.

Babywearing: Biomechanics Applied to the Shopping Cart

Mari Carmen thought that carrying the baby in her arms was enough.

Now she knows how to distinguish between:

• Stretchy wrap: a long elastic, rigid, or semi-rigid fabric that adjusts with knots to carry a baby.
• Ergonomic carrier: a pre-formed carrying system where you place the baby in a “seat” for easy and comfortable transport.
• Ring sling: an asymmetrical carry that consists of a fabric with rings, allowing for hip carrying, for example.
• Mei Tai: similar to a baby carrier but with “squared” straps.

And she says it with authority.

—Celia, if they are not in the “M” position, am I compromising their psychomotor development?

Indeed (Mari Carmen has done her homework on this topic too).

Ergonomic babywearing seeks to respect the natural posture of the baby (frog position: legs and hips in an “M” shape and back in a “C” shape) and the adult. It’s basic ergonomics.

And yes, there is babywearing consulting. Because if we’ve learned anything, it’s that preventing back pain is always a good idea.

Tribe and Postpartum: When the Mother Also Matters

Here Mari Carmen fell silent.

—Matrescence? Diastasis? Linea alba? I only knew I was tired.

Matrescence is the profound process of emotional, physical, and social transformation a woman undergoes when she becomes a mother. While it’s the most natural thing in the world, it’s quite brutal what we go through. It shakes identity, priorities, and expectations.

After childbirth, terms like:

• Pelvic floor: a group of muscles and ligaments that support the bladder, uterus, and rectum. Very important to take care of it before and after childbirth to avoid issues like incontinence, for example.
• Abdominal diastasis: excessive separation of the rectus abdominal muscles. It occurs in all pregnant women from week 35 of gestation but does not always persist in the postpartum period.
• Hypopressives: a pressure-free training technique that contributes to better recovery after childbirth, toning the abdomen and pelvic floor.
• Respected postpartum: the immediate period after childbirth where the focus is on the baby and the mother, respecting the rhythms of both.
• Obstetric violence: refers to practices carried out by health professionals that do not respect the rights and dignity of women during childbirth.
