Quick answers
Frequently asked questions
How do I know if a diaper fits?
The waistband sits just below the belly button, the leg cuffs are pulled out, and you can slide two fingers under the waist. Red marks or gaps at the legs usually mean it's time to check the size.
When should I size up?
Go by weight and fit, not age. Frequent leaks, red marks or tabs that barely reach the middle are the usual signs. Our sizing guide lists the weight range for each size.
How many diapers does a newborn use?
Often 8 to 12 a day in the first weeks, then fewer as they grow. Our guide breaks down how many you'll need by month.
What helps with diaper rash?
Frequent changes, gentle cleaning, letting skin air-dry and a barrier cream help most mild rashes. If it doesn't improve in a few days, or there's fever or blisters, call your pediatrician.
