If you find yourself spending a lot of time inspecting your baby’s diaper, you’re not alone. Many parents worry about the colour, consistency and/or frequency of their baby’s poops (stools). Your baby’s stools will change as he develops—and they may even change from one day to the next. They can vary depending on how old he is, whether he’s breastfed or bottle fed, and whether he’s started solids.

Answers to common questions about baby stools
What will my newborn's stools be like?
During the first 2 or 3 days after birth, your baby will pass meconium. Meconium is dark greenish-black and very sticky, almost like tar. This is a sign that your baby’s bowels are working normally.
What will my baby’s stools be like if I’m breastfeeding?
A breastfed baby’s stools can range in colour from a greenish-brown to bright or mustard yellow. The stools may seem grainy or curdled and loose in texture.

What stools should I expect my baby to have if I am formula feeding?
Formula fed babies generally tend to have firmer stools than breastfed babies. However, babies fed a formula with a fibre blend of galactooligosaccharides (GOS) and polydextrose may have softer stools than babies fed a formula without GOS and polydextrose. The stool colour of formula fed babies can range from pale yellow to yellowish-brown.
What do I do if my baby has diarrhea?
If he has more bowel movements than usual, and his stools are less formed and more watery, your baby might have diarrhea. He may have other symptoms, such as fever, loss of appetite, nausea, vomiting, stomach pains, cramps, and blood and/or mucus in his bowel movements. It can quickly lead to dehydration and might be a sign of an infection, so call your baby’s doctor if your think your baby may have diarrhea.
What do I do if my baby is constipated?
It is normal for some babies to poop more often than others. However, if your baby has bowel movements less often and his stools are hard and dry and difficult to pass, he could be constipated.
Other questions
To help relieve his discomfort, gently rub his tummy and then press his legs into his tummy and gently rotate them as if he were riding a bicycle. If you think your baby is constipated, or if you have any concerns about baby’s stools, talk to your baby’s doctor.
