How to Prevent Leakage from Nappies

The most common cause of leakage is fitting your baby with the wrong nappy size. So start by checking if the nappy 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 nappy size may appear to fit your baby, the amount of pee may have increased with his growth, so the nappy may not be able to absorb the larger amount of urine. For disposable nappies, the bigger the size, the better the absorbency. If you notice frequent leakages, it may be time to change the nappy to a larger size.
If there is leakage even though you have fitted the nappy properly on your baby, do a check for the following:

Are the leg gathers folded inwards?

Are the nappy tapes around the tummy fastened properly?

Are there any gaps between the nappy and baby's thighs?

Check that the size is right!

Struggling with nappy leakage?

Why is baby's nappy leaking?
Advice for leakages from different parts of the nappy

1. Back leakage

Causes

Gap between nappy and baby's back
Nappy tends to go out of alignment due to your baby's active leg movements. (Fairly common for Small size users).
Nappy is taped more to the front, leaving less coverage for the back.

Advice

When placing the nappy under your baby's bottom, make sure you pull the nappy high enough to prevent leakage. Raise the back portion slightly higher than the front portion and then fasten the tape diagonally downward.

2. Side leakage

Causes

The gathers around the legs may be folded inwards.
The position of the tape fastened is out of the marked area.
The tape has not been fastened evenly at both sides.

Advice

Make sure that the nappy edges are not folded and that tape is fastened evenly. 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 nappy. Try using one size bigger.

3. Thigh leakage

Causes

Leg gathers are folded inwards.
There are gaps around the thighs. (A gap is likely to appear between babies' thighs and the nappy as their legs are spread out when they are fastened into a child seat or pram can.)

Advice

Pull the nappy 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 nappy tape at a lower level, slightly slanted at an angle.

4. Tummy leakage

Causes

Nappy is too loose-fitting around the waist.
When your baby is lying on his tummy, pee tends to flow up towards baby's tummy.
(In the case of boys) The penis is pointing upwards.

Advice

Raise the front portion of the nappy slightly higher than the back portion and fasten the tape slanting upwards so that the belly button is hidden. For boys, make sure the penis is pointing downwards.
