Preventing Leaks With Cloth Nappies

Keeping Your Baby Dry and Happy

Leak-free cloth nappying is possible with a few simple techniques and by understanding the causes of leaks. Cloth nappies are a cost-effective and environmentally friendly option, but they can be frustrating when leaks occur. Below we will provide practical tips and tricks for preventing leaks in cloth nappies.

Main Causes of Leaks

One of the main causes of leaks in cloth nappies is a poor fit. If the nappy is too loose, it will not contain wee and poo effectively. Additionally, if the nappy is too tight, it can cause red marks, beyond the normal 'sock mark' and discomfort to your baby's skin. To prevent leaks, it is essential to find the right fit for your baby and adjust the nappy as they change shape and grow.



Top Tips for Preventing Leaks

  1. Use a waterproof cover: A waterproof cover will keep the wetness contained within the cloth nappy if you are using prefolds, muslins, flats, preflats, fitted nappies, terries, or even pocket inserts inside.

  2. Adjust the nappy for a snug fit: Make sure the nappy is snug but not too tight around the legs and waist. Leave room for two fingers at the waist to allow for comfortable movement and bending and tuck the elastics into the knicker line at the legs.

  3. Use a doubler or booster: An additional booster or doubler will provide extra absorbency and help prevent leaks. If you have a heavy wetter, choose a material such as bamboo or hemp (or blends of these two) as they will hold a large volume. If you have a flooder, or a baby that wees very quickly and a large amount, be sure to pair a fast absorber such as microfibre or cotton with a heavy absorber such as bamboo, hemp, organic cotton, or blends of these materials. 

  4. Check the nappy frequently: It is essential to check the nappy regularly, especially during nighttime and naps, to prevent leaks. To tell if the nappy is wet, you'll notice it may get a bit hard to the touch. If in doubt, simply take a peek inside.

  5. Try different types of cloth nappies: Different types of cloth nappies have varying levels of absorbency. Experimenting with different types can help you find the best option for your baby and prevent leaks. We suggest a mix of daytime nappies and a terry or fitted nappy for overnights paired with a wool or PUL/TPU cover to keep baby comfortable and dry.

  6. Properly launder the nappies: It is important to follow the manufacturer's instructions for washing the cloth nappies to maintain their absorbency and prevent leaks.


Leak-free cloth nappying is possible with a few simple techniques and understanding the causes of leaks. By finding the right fit for your baby, using a waterproof outer, adjusting the nappy for a snug fit, using a doubler or booster, checking the nappy frequently, trying different types of cloth nappies, and properly laundering the nappies, you can ensure that your baby stays dry and happy.
