Stop Diaper Leaks Today!

Stop Diaper Leaks. Guaranteed.

Is your child experiencing any of these problems: occasional or frequent diaper leaks at night or during naps, multiple nights of interrupted sleep, waking up cold and wet and leaving you with countless loads of extra laundry? (wetness creates discomfort, and it’s this discomfort that may wake your baby from a peaceful night’s sleep).

The fact is, if you have a child in diapers, there’s a good chance she/he needs some type of overnight protection against diaper leaks. Unfortunately, thousands of parents deal with this issue every night leading to many sleep deprived families.

Sposie Overnight Diaper Booster Pads guarantee to stop diaper leaks allowing your child to get the uninterrupted sleep needed for healthy development. Outside of the obvious hassles diaper leaks cause us parents, according to Michael J. Breus, PhD, giving your child the opportunity to sleep continuously through the night without being woken up, (for example by a leaky diaper or even a mid-night diaper change to try and avoid a diaper leak) is the first and foremost first step in ensuring your child’s brain develops correctly from the onset.

The problem: Diaper Gap

Babies come in all shapes and sizes, which is why one brand of diapers may work great for your neighbor’s child, but not for yours. One thing diapers do have in common is that they all create what we call “diaper gap”. The diaper gap is naturally created in the space between the baby’s bottom and the diaper. This “gap” is an intentional design of diapers (and unavoidable) because it creates an area for #2’s - good for the daytime, but usually not needed at night.

This empty space means that moisture is not absorbed into the diaper as quickly as it needs to be to avoid leaks. Therefore, even if the diaper fits snug around your child's waist and legs, there is a pool of standing liquid just asking to go somewhere other than where it’s originally intended to go. Add to that the pressure caused by your baby moving around on the mattress, it’s like a little tiny damn trying to hold back a sea of pee.

Can overnight diapers help?

Overnight diapers are similar to daytime diapers in appearance but with a marginally higher absorbing capacity. However, as one would imagine, these diapers come with a significantly higher price tag - which is the reason most parents choose to only use overnight diapers at night.

While overnight diaper brands may work for some children, most do not have enough absorbing power for particularly heavy wetters and even more fail to stop the root of what is causing the diaper leak in the first place.
