The most common cause of leakage is fitting your baby with the wrong diaper size. So start by checking if the diaper size is right for your baby. Note also that the amount of pee increases as your baby grows. By the time your baby is 12 months old, the amount of pee discharged in a day will be twice that of a newborn. While the diaper size may appear to fit your baby, the amount of pee may have increased with his growth, so the diaper may not be able to absorb the larger amount of urine.
For disposable diapers, the bigger the size, the better the absorbency. If you notice frequent leakages, it may be time to change the diaper to a larger size.
In addition, if there is leakage even though you have fitted the diaper properly on your baby, do a check for the following:


-
- There is a gap between the diaper and the baby's back.
- The diaper tends to go out of alignment due to the baby's active leg movements. (Fairly common for S size users).
- The diaper is taped more to the front, leaving less coverage for the back.

-
When placing a clean diaper under your baby's back, make sure you pull the diaper high enough to prevent leakage. The back portion should be in a higher position compared to the front portion. Fasten the tape from the top, slanting slightly.

-
- The gathers around the legs may be folded inwards.
- The position of the tape fastened is out of the marked area.
- The diaper tapes are asymmetrical at both sides when fastened.

-
Make sure the corner portion of the diaper at the waist level is not folded inwards. Stretch it out properly before fastening the tapes similarly on both sides. If you notice that the position where you fasten the tape is out of the marked area, it's time to change the size of the diaper. Try using one size bigger.

-
- The gathers around the thigh area may be folded inwards.
- There is a gap around the thigh area. (A gap is likely to appear between the legs and the diaper when you belt up your child in the child seat in the car or stroller, as your child's legs are spread out.)

-
Pull the diaper straight and high enough to reach the belly button area. Adjust the gathers around the leg area so that they fit properly around the crotch area. Make sure the gathers are pulled outwards. If the leakage continues when your child is strapped onto a seat belt, try to fasten the diaper tape at a lower level, slightly slanted at an angle.

-
- The waist area is too loose-fitting.
- When your baby sleeps on his tummy on the bed, leakage from the tummy area is likely to happen.
- In the case of baby boys, it is because the penis is pointing upwards.

When placing a clean diaper under your baby's back, make sure you pull the diaper high enough to prevent leakage. The back portion should be in a higher position compared to the front portion. Fasten the tape from the top, slanting slightly.
