How Often Do Babies Pee When They Sleep?

Having a newborn can be exhausting (duh). And when your little one has finally fallen asleep, you might be up wondering weird things like, how often does baby pee when they sleep? Hey, in the wild journey that's motherhood, no question is too weird. When your baby wakes up with a puffy diaper, meaning it's full of urine, that means it's time for a change. But what if your baby wakes up from a long night (wishful thinking) with a dry diaper. What does that mean? Oh, the questions of mom life.

According to Parenting, a newborn will wet eight to ten diapers a day. You might think that because your baby is sleeping as opposed to feeding, that he or she will pee less while sleeping. At least that's what some moms over at the Baby Center message boards thought. It's a good theory, but as of now there isn't any medical evidence to support it. According to The National Institute of Child Health and Human Development (NIH), newborns pee very little because they have such small bladders. It's common for newborns to go one to three hours without passing a drop of urine. Once your baby gets a bit older, his or her bladder grows, and so does the capacity for bladder control. So, older babies can go four to six hours without urinating. If the weather is very hot, NIH noted that you may see a decrease in the frequency of urination.

When your baby is about six to eight weeks old, Parents suggested you start putting bay to bed awake, but slightly drowsy. This has nothing to do with urination, but setting a sleep routine to establish healthy sleep habits. Part of that routine means not waking your baby to change a wet diaper. So, it's perfectly fine to let your little one get some shut eye with a wet diaper. Dr. William Sears explained in his book The Baby Sleep Book: The Complete Guide to a Good Night's Rest for the Whole Family, that because babies spend a good deal of time in a messy diaper, a wet diaper is a familiar sensation. In other words, it's not likely that a wet diaper will disturb your baby's sleep.
