Breastfeeding first days: what is normal, when to call
October 28, 2026
Breastfeeding in the first days is frequent and uneven, and that is normal. A newborn often wants the breast every 1 to 3 hours and at least 8 to 12 times in 24 hours, on very small amounts of first milk (NHS and AAP). Black tarry stools and some early weight loss are expected. Call today if your baby sleeps through feeds, seems hungry after most of them, or your milk has not come in by day 5 (AAP).
You will not get this perfectly right on day one, and you do not have to. Use the lists below as a map for the first five days, and call early when something on the second list shows up.
Is it normal for a newborn to want to feed constantly in the first days?
Yes. The NHS guide to the first few days of breastfeeding says that in the first week your baby may want to feed very often, as often as every 1 to 3 hours in the first few days. It gives a rough guide of at least 8 to 12 feeds, or more, every 24 hours during the first few weeks.
The American Academy of Pediatrics (AAP) uses the same figure in its guide to how to tell if your baby is getting enough milk: nurse at least 8 to 12 times every 24 hours.
What this feels like at 2 a.m. is a baby who finishes a feed and wants more within the hour. That is a baby doing the job, not a baby who is not getting enough. Feeds also come in small amounts at first. The NHS describes the first milk, colostrum, as very concentrated, so your baby needs only about a teaspoonful at each feed.
Make the nights easier before they start. Our guide to what to prepare before the baby arrives covers the gear and the set up for exactly these feeds.
What does each of the first five days usually look like?
Each day follows the same pattern: many small feeds, and stools that change color as milk arrives. The AAP gives the stool pattern day by day. Weight loss is covered under the next heading.
First day
Feeds: Frequent, short and small, about every 1 to 3 hours (NHS).
Diapers: 1 or 2 stools, blackish and tarry.
Second day
Feeds: Still very frequent. It can feel like you are feeding all day.
Diapers: 1 or 2 stools, still blackish and tarry.
Third day
Feeds: Frequent, still small amounts of colostrum.
Diapers: At least 2 stools that begin to look greenish to yellow.
Fourth day
Feeds: Frequent. Ask for a latch check if feeds look short or you hear no swallowing.
Diapers: At least 2 stools, greenish to yellow.
Fifth day
Feeds: Still 8 to 12 or more in 24 hours (NHS). Your breasts should feel as though they are filling with milk.
Diapers: Stools yellow and loose with small curds, at least 3 to 4 a day. The AAP also expects 6 or more wet diapers a day with nearly colorless or pale yellow urine by day 5 to 7 (AAP).
The AAP gives no firm wet diaper count for the first four days, so follow the stool color and the feeds in those days and ask for a weight check if you are unsure.
What feels alarming but is normal?
These are the things that frighten new parents most, and all of them are expected in the first days.
Feeding again within the hour. The NHS says every 1 to 3 hours is common in the first days (NHS).
Tiny amounts of thick first milk. About a teaspoonful a feed is enough at first (NHS).
Black, tarry first stools. The AAP lists blackish, tarry stools as the normal pattern on the first two days (AAP).
Some weight loss. The AAP says a baby should lose no more than 8% to 10% of birth weight in the first few days before starting to gain (AAP).
If a number on that list does not match what you see, you have found a reason to call, not a reason to wait.
Which signs mean call your clinician or a lactation consultant today?
Call today if you see any of these. The AAP's list of warning signs of breastfeeding problems is the source for the ones below. Do not wait for the next appointment.
Call today about your baby
Your newborn frequently misses feeds or sleeps through the night.
Your baby still seems hungry after most feeds.
Feeds are either very short or extremely long.
You do not hear frequent swallowing once your milk has come in.
After 7 days, fewer than 6 wet diapers and 4 stools a day (AAP).
At two weeks, your baby is under birth weight or has not started gaining at least 5 to 7 ounces a week.
Call today about you
After 5 days, your milk has not come in, or your breasts do not feel as though they are filling (AAP).
Severe engorgement, or breasts that stay full and hard after a feed.
Severe pain that gets in the way of feeding.
Call your baby's pediatrician or a lactation consultant, whichever you can reach first. Anything that worries you about your baby's breathing or color is a reason to call emergency services, not a feeding clinic.
The AAP also advises booking your newborn's first checkup no more than 48 hours after hospital discharge (AAP), because the weight check there is how you find out whether your baby is getting enough milk.
What helps in the first week at home?
Feed on cue, keep your baby close, and get a person to look at the latch early. The NHS says to speak to a midwife or health visitor if you are worried about breastfeeding or think your baby is not getting enough milk. In the US, that is your pediatrician, the hospital's lactation team or a private lactation consultant.
Watch the swallowing, not the clock. The NHS says if your baby seems to fall asleep before the deep swallowing stage of a feed, it may mean they are not well attached. Ask someone to check how your baby is latched.
Keep a rough tally for the first week. A scrap of paper by the bed works: feeds, wet diapers, stools. It turns "I think it is fine" into something you can read out on the phone.
Set up one feeding spot. A chair, a glass of water and a dim light within reach.
Ask for help before it hurts. Severe pain is on the call today list above.
Share the rest. Someone else can handle meals and laundry, so you feed and rest.
Once your baby moves on to solid foods, how much milk a baby needs after starting solids picks up where this leaves off.
How do I know my baby is getting enough colostrum?
Look at stools, feeds and weight. Stools should move from blackish and tarry on days 1 and 2 to greenish and then yellow by days 3 to 5, and your baby should feed at least 8 to 12 times in 24 hours (AAP). The weight check at the first checkup is how you confirm it.
Is it normal for a newborn to lose weight at first?
Yes. The AAP says a well fed baby loses no more than 8% to 10% of birth weight in the first few days before starting to gain (AAP). A baby who is under birth weight at two weeks, or gaining less than 5 to 7 ounces a week by then, needs a call.
Should I wake a sleepy newborn to feed?
A newborn who frequently misses feeds or sleeps through the night is on the AAP's warning list, and newborns need to nurse at least 8 to 12 times in 24 hours (AAP). If your baby is too sleepy to feed regularly, offer the breast and call your pediatrician or a lactation consultant the same day.
When does my milk come in?
The first days give colostrum, the thick first milk. Your breasts should feel as though they are filling with milk by day 5 (AAP). If they do not, the AAP says to call, because that is one of its warning signs of a breastfeeding problem.
