How to Prevent Your Baby’s Nappy from Leaking:

Most leaking nappies are caused by having the wrong sized nappy or incorrect fit on your little one. With these simple questions, we can help you understand why your baby’s nappy is still leaking, and suggest some of our top tips for getting the right size and fit. Ask yourself:

  1. Where are the leaks coming from?
    • Leaks from the leg generally indicate the nappy is too big, so we’d recommend sizing down. Leaks from the back/waistband indicate the nappy is too small, or that the nappy tabs are too tight. We’d suggest sizing up or trying to attach the grip tabs closer to your baby’s hips, rather than in toward their belly button.
  2. Are you experiencing leaks overnight or during the day?
    • Sizing up can often help with overnight leaks. Leaks throughout the day may suggest the nappy isn’t correctly fit, so keep reading for our tips below.

Finding the Right Nappy Size to Stop Leaks:

Finding the right nappy size will help reduce the chance of leaking nappies for most children. Rascals Premium Nappies feature a unique design and fit which provide up to 12 hours of leak protection. Because of this, we recommend using our Size Guide to get the perfect fit and reduce the chance of nappy leaks and blowouts.

What makes Rascals Premium Nappies different?

Rascals Premium Nappies are Our #1 Absorbing Nappy[1] and provide 12 hours of advanced leak protection[3] so your little one can be comfy and dry, all day and night. Here’s how our premium features ensure the correct fit on your baby:

How our nappies should fit:

  • Rascals Stretchy High-Back Waistband™: Designed to keep blowouts contained, our waistband is designed to sit comfortably on your baby’s back. Our unique fit means our nappy might sit a little higher than other brands. In line with their belly button is about right.
  • Leg cuffs: Made from a premium fiber blend to be soft on skin, our leg cuffs should sit flat on your baby’s skin and be untucked when the nappy is worn. The ruffle-like material should be facing out.
  • Triple leak guards: Designed to catch any sneaky leaks, our leak guards (elastic-like material) should sit flat on your baby’s skin. If they’re tucked or folded in, leaks might be able to escape!
  • Strong grip tabs: Designed to be strong not stretchy, our resealable tabs are designed to stay in place and help you get the perfect fit. They should sit comfortably at your baby’s hip when fastened (not covering the Rascals logo on the front of the nappy).
  • Unique Hydrolock Core™: Designed to hold up to 25x its weight in liquid[2], our Unique Hydrolock Core™ traps moisture within the core so it feels dry on your baby’s skin and helps prevent leaks and skin irritation.

4 Tips to Have the Perfect Rascals Nappy Fit:

  1. To check you’ve got the right fit, run a finger along the inside of the waistband. If you can fit more than one finger inside, the nappy is too loose. If you can’t fit a finger inside, it’s too tight.
  2. Ensure the strong grip tabs are securely fastened on your baby’s hips. Our strong grip tabs are resealable and are designed to sit further apart when fastened onto the front of the nappy. For reference, you should still be able to see the Rascals logo on the front of the nappy.
  3. Our unique fit means that when the nappy is on your little one, it should be snug on their tummy (pulled up just under their belly button) and at the same level on their back.
  4. Rascals Stretchy High-Back Waistband™ is designed to sit higher on their back, and helps contain sneaky leaks and blowouts

FAQs: Baby Nappy Leaks

A nappy leak often occurs due to an ill-fitting nappy, over saturation, incorrect sizing, or when the nappy reaches its absorption limit.

To prevent nappy leaks or nappy leaking during the night, use highly absorbent nappies designed for overnight use. Ensure a snug fit and limit liquids before bedtime.

Ensure the nappy fits properly around the legs and waist. Consider trying different nappy styles or brands to prevent ongoing nappy leaks or nappy leaking.

If frequent nappy leaks or nappy leaking occurs, consider transitioning to a larger nappy size for a better fit and improved leak protection.

Opt for nappies with stretchy sides for a secure fit during movement. Check and readjust the nappy as needed during active periods to prevent nappy leaks.
