Babies Diapering How often should I change my baby's diaper? By Parents Editors Published on July 2, 2015 Share Tweet Pin Email Q: How often should diapers be changed? A: Well, poopy diapers should be changed as soon as it is clear that your baby has left you a gift. Poop can irritate the skin or worse, be a set-up for a bladder infection, particularly in baby girls. With super-absorbent diapers, it is probably okay to leave a wet diaper on for a little longer, especially if your baby is sleeping through the night; there is no need to wake up your little one to change a wet diaper. But in general, if you spot a wet or soiled diaper, it is time to change it. Answered by Dr. Ari Brown Was this page helpful? Thanks for your feedback! Tell us why! Other Submit
