What color is the poop?
Common signs, and what the guidance says to do
Usually normal
Black, sticky poop in the first 2-3 days is meconium, which is normal. If it is still black on day 5, or black poop comes back later, call your doctor.23412
Usually normal
Dark green-brown 'transitional' poop is typical around days 3-4 and usually means milk is getting through.34
Usually normal
Mustard-yellow, seedy, runny poop is typical of breastfed babies. It is not diarrhea.23
Usually normal
Thicker, stronger-smelling poop like this is typical with formula.23
Usually normal
Usually normal. Some formulas can make poop dark green. Call if it is green and watery with fever, or your baby seems unwell.23
Watch and log it
Common in the first few days, a sign of concentrated urine. If they keep appearing after day 3-4, or come with few wet diapers, call your doctor or midwife: your baby may need more milk.3
Guidance: call your doctor today
Often a tiny tear in the skin around the bottom, but always check with your doctor the same day. Lots of blood, or a baby who seems unwell: get help now.2312
Guidance: call your doctor today
Pale poop can be a sign of a liver problem, such as biliary atresia, that needs treatment quickly. Call your doctor today and show them a photo of the diaper.56
Guidance: get medical advice now
Very watery poop, much more often than usual, can be diarrhea, and newborns lose fluid fast. Get medical advice now: call your doctor right away (in the UK, 111), especially with a fever, vomiting or fewer wet diapers.3913
Watch and log it
Hard pellets now and then can happen with formula: check you are mixing it exactly as the label says. Call your doctor if it keeps happening, your baby seems in pain or is feeding less, or there is blood.23

The details
Why diapers are the best feeding check
You can't measure breast milk, but what goes in must come out. Steady wet and dirty diapers in the first weeks are one of the clearest signs that a baby is feeding well. Midwives and doctors ask about them for exactly that reason.
Modern diapers absorb so well that a wet one can feel almost dry. A heavy wet diaper holds about 3 tablespoons (45 ml) of fluid. To learn the feel, pour 3 tablespoons of water into a clean, dry diaper and compare. Some diapers also have a line that changes color when wet.
Breastfed poop is usually yellow, runny and seedy, and has a mild smell. Formula poop is usually tan or brown, thicker, like peanut butter, and smells stronger. Both are normal. A sudden change in color with fewer wet diapers, fever or a baby who seems unwell is worth a call.
In the first 6 weeks, a breastfed baby should poop at least twice a day. Fewer can mean not enough milk, so call your doctor or midwife. After about 6 weeks, some breastfed babies go several days without a poop. If it is soft when it comes and your baby is feeding and wetting well, that is normal.
Change diapers often, clean with water or gentle unscented wipes, let the skin air-dry, then apply a thick barrier cream such as zinc oxide. Call your doctor if the rash has blisters or pus, spreads beyond the diaper, or does not improve after 2-3 days.
At least 1 on day 1, 2 on day 2 and 3 on day 3, then at least 6 heavy wet diapers every 24 hours from day 5-6 onward.14
How many poopy diapers should a newborn have?
At least 1 on days 1-2, then at least 2 a day from day 3. Many breastfed babies poop after almost every feed in the first weeks.1234
When should newborn poop turn yellow?
Usually by day 4-5, as the black meconium clears and milk comes through. If poop is still black or dark green on day 5, call your doctor or midwife.124
Is green poop normal in newborns?
Usually, yes. Some formulas can make poop dark green. Call your doctor if it is green and watery with fever or the baby seems unwell.23
Why is pale or white poop dangerous?
It can mean bile is not reaching the gut, as happens in biliary atresia, a rare liver condition that is much easier to treat when found early. Call your doctor the same day.56
