How to check the fit
01
Check the waistband
It should sit just below the belly button with two fingers of room - no red marks.
02
Watch the leg cuffs
Cuffs should be out, not tucked in. Gaps at the thighs are the #1 cause of leaks.
03
Size up when…
You see marks, frequent leaks, or the tabs reach the edge. Babies often size up around 6-8kg.
