What to do if your baby's weight falls between two diaper sizes?
Don't worry - there's a couple of tricks you can use to find the right size to make sure your baby is comfortable & happy:
- Make sure the upper waistband fits directly underneath you baby's bellybutton.
- There should be minimal room between the fittings around the diapers and your baby's thighs. Once you put on the diaper, run two fingers between the thigh leggings and the diaper to smooth out all space and prevent any leakage.
- Once the diaper has been properly fitted, there should be enough space to fit two fingers between the waistband and your baby. It should be snug, but not tight.
- After using the diaper, if your baby has any irritations/rashes, consider switching the diaper size immediately.
