My baby's diaper keeps leaking from the sides (especially with pant style). What am I doing wrong?

Moms say leakage is often due to fit/size issues, especially for boys. Taped diapers can reduce leaks if flaps and leg ruffles are positioned correctly.

💡Quick Answer

  • Check diaper size based on baby's weight (fit matters most)
  • Pull out leg ruffles so they're not tucked in
  • For taped diapers: fold/flare the inner flaps correctly
  • Pant styles may leak more if baby is lean or very active
  • Change every ~3–4 hours (or sooner if heavy pee)

⚠️ Caution:Frequent leaks can cause rashes—monitor skin and adjust fit/brand. If leaks continue despite correct sizing, try a different brand or style.

🤔What Parents Worry About

Parents worry they're doing something wrong, especially with boy babies. Moms say it's usually a size/fit issue and pant styles can leak more.

Community Answers from Moms(10)

Here's what moms in our community shared based on their own experience.

  1. 1

    Pant style often leaks more — taped diapers feel more secure for many babies.

  2. 2

    Leakage with boys can happen due to anatomy if the diaper is even slightly loose.

  3. 3

    Make sure the leg ruffles are out (not tucked in) and fold/flare out the front flaps in taped diapers.

  4. 4

    Diapers don't cause UTIs. A wet langot/nappy left on is more likely to cause a rash than a good diaper that's changed frequently, because langots have no absorbing power. Dermatologists say a wet nappy must be changed instantly.

  5. 5

    Consider nappy/diaper-free time during wake windows and diapers during night and longer sleep stretches; the baby's sleep matters.

  6. 6

    In the first ~3 months, diapers reduce the risk of cold (and pneumonia from chilling), especially in cold weather when going diaper-free exposes the baby.

  7. 7

    Pampers newborn diapers have a wetness-indicator line (yellow to blue). Change every 3-4 hours regardless, and immediately after a poop, even at night. Pampers pants are quieter and stay in place.

  8. 8

    Some parents use Pampers at night and Medplus Kiddos diaper pants during the day since pants stay in place better, with no rash issues.

  9. 9

    Apply B4 Nappi cream generously as a barrier; use Desitin if a rash appears.

  10. 10

    For cloth options: SuperBottoms UNO claims 4-5 pees (some find it holds fewer before the baby fusses); their dry-feel langots claim one pee but can hold two, though they're warmer/thicker. Plain langots are more economical. Advanso is another good brand used alongside SuperBottoms.
