The Scoop on Baby Poop

Week 4

If it seems like you're constantly changing diapers, you're not imagining it. By the end of this year, you'll have changed 2,300 diapers! Parents of twins -- double that number. Triplets ... you get the picture.

So you're not surprised when you open your baby's diaper, here's what to expect.

Breastfed babies:

  • Make yellow poop that's speckled with little seeds--like mustard
  • Poop one or more times a day, usually after they eat

Formula-fed babies:

  • Have tan, yellow, or greenish poop
  • Poop once a day, sometimes more often

What's normal:

  • Poop can come in a rainbow of colors, changing to yellow, green, or brown.
  • Some babies don't poop for a day or two -- even a week. You don't need to worry as long as your baby is still eating and gaining weight.

What's not normal (time to call your doctor):

  • Poop that is filled with mucus, water, or blood could be a sign of an allergy or infection.
  • Solid, hard poop means your baby is probably constipated.

Your Baby's Development This Week

You've seen a real transformation in the last month. Your little one has changed from a tiny newborn into a more active -- and interactive -- baby with a budding personality.

As she hits the big 1-month mark, here are just some of the new things she's able to do:

  • Move her head from side to side while lying on her tummy
  • Turn her head toward the sound of your voice
  • Coordinate her movements well enough to bring her hand to her mouth
  • Focus on a toy that's 12 inches away, although her eyes may still cross and that's OK
  • Recognize the smell of her mother's milk

Week 4 Tips

  • If your baby is constipated, try mixing a teaspoon of prune juice with breast milk or formula.
  • Save the baby wipes for messy poop clean-ups. A damp washcloth is good enough for cleaning after a wet diaper.
  • Your baby's neck muscles are getting stronger, but she still can't hold up her head on her own. Don't forget to support her neck whenever you carry her.
  • Do not hold your baby while you are eating or drinking anything hot.
  • When your baby seems ill, take her temperature with a rectal thermometer -- it's most accurate at this age.
  • A rectal temperature at or above 100.4 degrees Fahrenheit is a sign your baby could be sick. Call the pediatrician right away.
  • Your baby's one-month birthday is time for a well-baby visit. At the appointment, the doctor will measure your baby, check her health, discuss vaccines, ask how she's been eating and sleeping, and give some guidance for developmental goals.
  • You've been focused on your baby for a month now. Don't forget about your partner. Get a babysittter so you can get some time alone with your partner.
