Leaks usually have a simple cause. Start with size and fit, then move to technique.
1) Wrong size: too small overflows, too big gaps. 2) Cuffs tucked in—fluff them out. 3) Tabs uneven—fasten symmetrically. 4) Diaper too low—pull the back panel higher. 5) Compression leaks—try a larger size at night. 6) Heavy wetter—consider higher absorbency. 7) Timing—if leaks happen near the next change, shorten intervals.
A quick test: after an hour, check the waistband and legs. If it sags, size may be too big. If it’s very full quickly and leaves marks, it may be too small. One careful refit solves most leak problems.
