Yes all Luvs diaper sizes come with a wetness indicator on the front of them.
The wetness indicator is helpful to see when it's time for the baby or toddler to be changed into a new diaper.
However although the wetness indicator may change color with a slight amount of pee it does not mean you have to change the diaper right then.
The Luvs diapers can last for 3 to 4 hours before they need changed depending on the age of your baby or toddler.
Luvs diapers are really absorbent and hold the wetness away from the baby or toddlers skin.
I always waited until my kids diapers were saturated with pee and filled up.
The kid will not feel any wetness unless the diaper is leaking and the urine will not cause them a rash until it starts turning into ammonia which takes longer than 4 hours for it to happen.
