How long can baby go without pooping? There is no ONE, simple answer to this question.
This article covers both normal reasons for a newborn baby, breastfed, or formulafed baby not pooping, and reasons related to illness. We go through safe remedies (when needed), important constipation signs, and when to call the Doctor.
Fully breastfed as well as formula-fed babies sometimes stop pooping for several days. This can seem worrying and it can be.
If your baby is not pooping, here’s how to know if it is normal or due to constipation. And, of course, what to do about it!
Reasons & Remedies When Your Baby Isn’t Pooping
Before I became a mom, it never crossed my mind how much time I would spend worrying about my children’s bowel movements. But I sure did. A lot happens during the first year, and a baby’s bowel movements will change a lot as the baby grows and his or her diet changes.
One of the more surprising things that happen, is babies that stop pooping completely for several days. It is easy and completely rational to believe this to be constipation. And it can be. But it also doesn’t have to be constipation – it can be completely normal too!.
In this article…
How Often Does a Baby Poop
First of all, it is important to know how often the average baby will poop depends on his or her age as well as on if being breastfed or formula-fed:
- A newborn baby, from day 5 or 6 of living, may poop after every feeding.
- At 1-month-old, the average is still some 4 times per day.
- By the time your baby is 2 months old, the average has dropped to 1 time per day.
- At 3 months, a fully breastfed baby may go for up to 10 or 14 days without pooping. They grow rapidly and digest practically everything they consume. This can continue until the baby is introduced to solid baby food.
- Formula-fed babies should continue pooping more or less every day.
Remember that the variation can be quite large and your baby is not likely to be constipated unless you notice some of the symptoms described below.
As you can see, there is no ONE correct answer to the question of how long can a baby go without pooping.
At 3 months, a fully breastfed baby may go for up to 10 or 14 days without pooping.
Breastfed, formula-fed, or solids fed baby not pooping?
Breastfed baby not pooping
There’s a major difference in the risk of constipation between breastfed babies and those on formula.
If you are breastfeeding and if your baby has had normal breast milk poop earlier, but your baby is not pooping now, chances are that he or she is only going through a growth period and therefore actually absorbs pretty much everything he eats.
Also, at around 4 weeks of age, a baby’s digestive system begins to mature and the number of bowel movements usually decreases, especially if the baby is breastfed.
If your baby seems completely happy and eats and urinates, just as usual, there is probably nothing you have to do. The poop will come.
Formula-fed Baby Not Pooping
If your baby is formula-fed, the risk of constipation is higher.
Formula-fed babies are more prone to become constipated because the formula is much harder to digest than breast milk.
Also, the formula can’t be as fully digested as breastmilk, so formula-fed babies, regardless of age, should have quite regular bowel movements.
Milk protein allergy is maybe not a common, but a possible reason for constipation in formula-fed babies.
A formula-fed baby should not go several days between pooping; for them, it can be a sign of constipation.
Newborn Baby Not Pooping – 3 Reasons
1. Hirschsprung’s disease
Regardless of if your baby is breastfed or formula-fed, it is important to know when your baby started having constipation problems and if he or she passed meconium in the first 36 hours of his or her life.
If the meconium passage was delayed and your baby has been having constipation since birth, one of the possible reasons for constipation might be Hirschsprung’s disease.
This is a condition caused by the absence of neural ganglia in the terminal bowel regions. The absence of the ganglia leads to decreased bowel movement and hence leads to constipation.
The condition is usually screened for by performing a rectal exam in a constipated child during a routine pediatric visit. (You can read more about Hirschsprung’s disease here at Mayo Clinic. (Opens in new window)
2. The normal first few days
However, it is worth repeating that a newborn baby that has passed meconium is not likely to poop very frequently during the first few days – simply because they don’t eat very much. But after 5 – 6 days, your newborn baby should be pooping several times per day.
3. Newborn not pooping but farting
A common situation is a young or newborn baby that is not pooping but passing gas. Unless your baby is showing signs of constipation or illness, this is highly likely to be a normal newborn immature digestive system.
The baby will fart more often than poop, and will probably also strain a bit to poop, even with loose stools. This is nothing to worry about or do something about.
Constipation after Starting Solids
It is very common that babies become constipated when introduced to solid foods. This is especially true for breastfed babies since their digestive system isn’t used to anything but the very easily digested breastmilk.
The introduction of rice cereal is a known reason for baby constipation. Cow’s milk is another one.

Signs of constipation (and not) in babies
Here are some signs of constipation to look for:
- In a newborn, firm stool less than once a day with straining and difficulty passing them
- In older babies, firm stools less often than 7 days for breast-fed babies and 4 days for bottle-fed babies
- Dry, hard stools and pain on passing them
- Hard, pebble-like stools passed by a baby who strains during a bowel movement
- Signs of blood along the outside of the poop
- Belly pain along with hard, infrequent stools
How to Mitigate Baby Constipation (9 Remedies)
While it is normal for babies to strain from time to time to move the stool along through the intestines, crying hard when trying to poop is not.
1. Baby Massage for Constipation
If you want to do something to help your baby while straining, try holding his or her knees against his or her chest to help your baby “squat”. This is also very effective for tummy pain to release gas.
Here are some more tips for efficient baby massage.
2. Change the type formula
If your baby is formula-fed you can experiment with different types of formula to find the one that has the least tendency to result in constipation. For some babies, soy-based formulas work better. For others, a hydrolysate formula, such as Nutramigen (link to Amazon) can make a real difference.
3. Feed smaller amounts
You can also feed your baby smaller amounts of formula more frequently, to help the intestines cope with the formula. Twice as often is a rule of thumb.
4. Double-check how much formula powder you use
Make sure that you don’t add too much formula powder when preparing the formula. Take care not to overfill or tightly pack the scoop.
5. A bit of water
You can also try offering your baby some extra water – about 1 oz once or twice a day. However, don’t give water very young babies.
6. More breastmilk
If you breastfeed at all, you can try to increase the share of breast milk your baby gets. Breast milk is a great laxative.
7. A q-tip
Another short-term option, that can be used once in a while, is to insert a q-tip very gently into your baby’s anus. Sometimes that is enough to trigger the bowel movement. Just don’t make it a habit; the baby needs to learn how to poop without your help.
8. Foods that soften the stools
For babies that have been introduced to solids foods, make sure you feed your baby foods that soften stools rather than the opposite
9. Baby laxatives and glycerin suppositories
There are also baby laxatives or glycerin suppositories available, but don’t use them more than as a last resort. It is much better to try to change what your baby eats than to use short-term solutions like these are.
Baby Not Pooping – Call the Doctor if…
If your baby is a few days old and has not pooped regular breast milk or formula poop, definitely call a doctor, to rule out any blockage and make sure your baby eats enough.
For a newborn baby that has pooped and then stopped, I would contact a pediatrician if it has been a couple of days since your baby pooped, regardless of if the baby is breastfed or formula-fed. This is to get advice on possible treatment for constipation and to make sure that your baby is completely healthy.
For older babies, if they are in pain (regardless of if the poop is hard or not), a doctor should assess the situation.
Blood in poop, beyond some streaks, should also be assessed. (You’ll find more guidelines on blood in your baby’s poop here.
Finally, if your baby continues to be constipated despite your efforts to adjust his or her diet, this is another good reason to discuss the situation with a pediatrician. Your baby may be allergic to milk protein or lactose intolerant, for example, and need a new type of formula. (Read more about milk protein allergy and different formulas here.)
Don’t use baby laxatives or glycerin suppositories without consulting a doctor first. It may be completely unnecessary.
