Diapers and digestion
Last reviewed · 3 min read · 8 sources · Plain-text version
What's in the diaper as month one ends: the colors that are fine, how often is normal, the two colors that mean call, and your own digestion too.

You've changed a few hundred diapers by now and know this baby's output better than anyone. Today is a short guide to reading it as the pattern changes, plus a word about your own insides.
Heart
A diaper change is a conversation, not a chore. Back-and-forth talk is at the heart of serve-and-return brain building (Harvard Center on the Developing Child). Your baby gets several changes a day, which makes the changing table the most reliable classroom in the house. Today's activity adds one thing to the narration: naming the body.
Head
Color first. After the first few days, mustard yellow is typical for breastfed babies, and yellow-tan with hints of green is typical for formula-fed babies (AAP). Green stools on their own aren't a cause for alarm (AAP).
Two colors are always a call. White or very pale poop can be a sign of a liver problem, so call your pediatrician as soon as possible. Red poop, or black poop after the first few days, can mean blood, so call about that too (AAP).
Body
How often varies a lot, and it often changes after the first few weeks. By 3 to 6 weeks, some breastfed babies poop only once a week and are still healthy, as long as the stools are soft and the baby is feeding well and gaining steadily. Formula-fed babies should have at least one bowel movement a day (AAP). So if your breastfed baby's daily count is dropping around now, that can be the new normal, not a problem.
Wet diapers are the steadier signal. By 5 to 7 days old, a breastfed baby should have 6 or more wet diapers a day with pale urine (AAP), and that should hold from here on.

The narrated diaper change, part two
Time: Every diaper change today · The narrated diaper change in the guide
Look at your baby's face and say what you're doing: "Tabs open. Here comes the cool wipe."
Name body parts as you go: "Here's your knee. Here's your other knee. Here's your belly."
Touch each part as you name it, then pause as if waiting for a reply.
If they coo, squeak, or stare, answer back.
Make it work:By about one month, many babies may look or turn toward familiar voices (AAP). Yours is the voice that comes with the warm hands.
Watch for
Normal
mustard yellow, yellow-tan, or greenish stools.
Call your pediatrician as soon as possible
for white or very pale poop, and call for red poop or black poop after the first few days (AAP).
Normal
fewer dirty diapers than a couple of weeks ago in a breastfed baby who's feeding well and gaining; formula-fed babies should still go at least once a day (AAP).
Call your pediatrician right away
if fewer stools come with poor feeding or fewer wet diapers (AAP).
Normal
6 or more wet diapers a day with pale urine.
Call your pediatrician right away
if there are fewer wet diapers than expected (AAP).
For you

Your own digestion deserves a thought. For constipation after birth, the Office on Women's Health suggests plenty of water and fresh fruits and vegetables (Office on Women's Health). Keep a full water bottle at every feeding spot; you'll drink what's in reach.
Bleeding should be well along its course: it goes from red to pink to yellow or white, and may last up to 6 weeks (MedlinePlus). Call your provider if the discharge gets heavier or smells foul (MedlinePlus), and seek care right away for severe belly pain that doesn't go away (CDC).
If you're the partner: the water bottle is your job. Fill it before she asks.
