Newborn Feeding: What Actually Happens in the First 48 Hours
Your baby has never eaten before. Not once in their entire existence. They came from a place where nutrition was delivered via a tube in their belly button, the catering was automatic, and no one had to figure out latch technique. Now they are on the outside, and everyone โ including them โ is slightly bewildered.
This is normal. This is expected. This is not a sign that you are doing it wrong.
Here is what actually happens.
## The First Hour: The Golden Hour
If you and your baby are both stable after birth, the recommendation is skin-to-skin contact within the first hour. This is not just a nice photograph. Skin-to-skin contact within the first hour:
- Stabilises your baby's temperature, heart rate, and blood sugar
- Stimulates the release of oxytocin (the bonding hormone) in both of you
- Triggers your baby's instinctive feeding reflexes โ the rooting reflex (turning toward the nipple), the sucking reflex, and the swallowing reflex
Your baby may not feed in the first hour. They may just lie on your chest and stare at you with the expression of someone who has just arrived in a country where they don't speak the language. This is fine.
## Colostrum: The First Milk
In the first two to three days after birth, your breasts produce colostrum โ a thick, golden, concentrated fluid that is produced in very small quantities (2-10ml per feed) and is one of the most nutritionally dense substances your body will ever make.
Colostrum is small in volume because your baby's stomach is the size of a marble. A marble does not need a litre.
Colostrum contains:
- Immunoglobulins (especially IgA) โ antibodies that coat your baby's digestive tract, providing immediate immune protection
- Growth factors that stimulate your baby's gut development
- White blood cells (leukocytes) โ literally living immune cells that formula cannot replicate
- A mild laxative effect โ which helps clear meconium (the thick, dark first stools) from your baby's bowel
Your mature milk will come in around day 3-4, with engorgement (breast fullness, sometimes significant) typically peaking around day 4-5. This is normal and temporary.
## How Often to Feed
Newborns need to feed 8-12 times per 24 hours โ roughly every 2-3 hours from the start of one feed to the start of the next. This is not negotiable and is not optional. Frequent feeding in the first days:
- Stimulates your milk supply (supply is driven entirely by demand)
- Keeps your baby's blood sugar stable
- Prevents jaundice from worsening (feeding helps flush bilirubin)
In the first 24 hours, some babies are drowsy from the birth process and need to be woken to feed. Wake your baby at least every 3 hours if they have not asked to feed. Signs a sleepy baby is ready to feed: rapid eye movements under closed eyelids, mouth movements, small hand-to-face movements. These are feeding cues. You do not have to wait for crying.
## Breastfeeding: Latch Basics
A shallow latch is the root cause of most breastfeeding pain and most supply problems. A good latch means:
- Baby's mouth covers most of the areola (the dark area), not just the nipple
- Baby's chin is pressed into the breast
- Baby's nose is clear (not buried in the breast)
- You hear swallowing, not clicking
If feeding is painful beyond the first 30 seconds of each feed, ask for a midwife or lactation consultant to check the latch. Pain is your body's signal that something needs adjusting. It is not something you push through indefinitely.
## Formula Feeding: What You Need to Know
If you are formula feeding from birth, or supplementing, the standard newborn formula volume is:
- Day 1: 30-60ml per feed, 8-12 feeds per 24 hours
- Day 2-3: 45-90ml per feed
Follow the tin instructions exactly for preparation. Do not add extra powder (it does not help the baby gain weight faster โ it stresses their kidneys). Do not add extra water. The ratios are carefully calibrated.
## The Weight Loss Every Parent Worries About
Newborns lose weight in the first few days after birth. This is expected, normal, and not a sign that feeding isn't working. Most babies lose 5-7% of their birth weight in the first three to four days. Up to 10% weight loss is within normal range. Your midwife will weigh your baby on day 3 and day 5 to track this.
Most babies regain their birth weight by day 10-14. If yours takes a little longer, it does not mean failure. It means they needed a bit more time.
## When to Call Your Midwife
Contact your midwife or health worker if:
- Your baby is not having at least one wet nappy by 24 hours, or at least three by 72 hours
- Your baby loses more than 10% of birth weight
- Your baby shows signs of jaundice (yellow skin, yellow whites of the eyes) before 24 hours or it is worsening after day 3
- You are in significant pain with every feed and adjusting the latch is not helping
- Your baby seems uninterested in feeding for more than 4-5 hours at a time in the first week
You are learning something completely new. Your baby is also learning something completely new. The first 48 hours are not the standard by which the whole journey is measured.

Around the World
Cultural practices & traditions โ medically contextualised
๐
West African
In many West African cultures, colostrum (the first breast milk) was historically discarded in some communities, as it was considered 'old' or 'dirty' milk. We now know colostrum is extraordinarily valuable โ it is packed with immunoglobulins, growth factors, and white blood cells that cannot be replicated in formula. If you encounter this belief in your community, it is worth a respectful conversation with a health worker.

South Asian
In India and Pakistan, a first food called 'ghutti' โ made from honey, ghee, or herbal mixtures โ is sometimes given to newborns before breastfeeding begins. The WHO strongly advises against giving anything (including water, honey, or herbal mixtures) to newborns before 6 months. Honey in particular carries risk of infant botulism, which can be fatal.
๐ฏ
East Asian
In Japan, China, and Korea, the postpartum practice of 'zuรฒ yuรจzi' (sitting the month) involves extended rest and dedicated lactation support, often from a trained professional called a 'yuรจsวo'. The emphasis on feeding frequency and maternal rest in this tradition aligns closely with modern lactation guidance.
๐ด
Caribbean
In many Caribbean families, 'grip water' (gripe water) is given to newborns almost immediately after birth. Modern gripe water formulations without alcohol are generally considered low-risk, but the original formulations contained up to 3.6% alcohol and sodium bicarbonate โ not appropriate for newborns. Always check the ingredients and check with your health worker.
๐ฆ
Indigenous / First Nations
Many Indigenous communities across the world have sustained breastfeeding rates significantly higher than the global average, partly due to intergenerational knowledge transmission and community-based support structures. The WHO recommends exclusive breastfeeding for 6 months and continued breastfeeding for 2 years or beyond โ a standard that indigenous communities have maintained for millennia.
