When your diaper is leaking from the front it's often a sign that the diaper is not fitted properly or is too small or not fastened secure enough around your waist.
When the diaper is too small or it is not fastened tight enough or secure enough around the waist it can leave gaps and allow pee or urine to escape out toward the front of the diaper.
Urine can leak out the from of the diaper when the diaper is also positioned too low on your body and not reach high enough around your belly button.
Ensure the diaper is positioned high enough up on the body and covering your belly button or at least near your belly button.
And ensure the tabs are securely fastened so that the diaper is tight enough but not too tight.
And make sure the diaper you're wearing is the right size and not too large or too small.
In some cases you may need a slightly larger diaper if you constantly leak out of the diaper but don't go too large as that can make for more leaks and make the diaper uncomfortable to wear.
