According to Potty Training Concepts, there isn’t a right age for a toddler to begin potty training. When a child demonstrates that he’s ready, though, parents can use tools to make the process easier and cleaner. Plastic underwear can prevent leaks and help children make the transition from diapers to wearing regular underwear full-time.


Plastic pants are often used when toddlers are potty training and parents are worried about accidents. These pants have a plastic feel and are usually made with an outside waterproof polyurethane laminate (PUL) fabric.


Plastic underwear can come as all-in-one, where the underwear is also connected to outer plastic fabric. These types of underwear have an inner layer of knit cotton fabric that sits next to children’s skin. The outer layer is a plastic that holds in wetness. Other plastic underwear are made of a single plastic layer that goes over traditional children’s underwear. These are sometimes called pull-on pants. Some PUL plastic covers also come with Velcro so that parents can put them on much like they would a diaper.

Using Plastic Underwear

Parents can use plastic underwear in several ways. Parents could encourage their toddler to either quit using diapers cold turkey and just switch to either all-in-one plastic pants models or underwear with single-layer plastic pants covering them. Children might find that they’re able to feel the wetness better and localise the muscles used in urination when they're switched to underwear. Other children might need a more gradual approach. For instance, they could aim to be dry for a few hours a day. Plastic pants will help during this transition during this time, particularly during outings and in a car.


Dr. Sears of recommends taking the pressure off children when it’s time to potty train. Children will learn to go independently when their muscles are ready.

Time Frame

<p> says that children gain control over their muscle in four steps: nighttime bowel control, daytime bowel control, daytime bladder control and nighttime bladder control.

Along with bladder control, parents should also watch for other signs that their child is ready to being potty training and possibly using plastic underwear. A toddler should have the motor skills to be able to undress him or herself, pull his or her pants down and pull his or her underwear down, Potty Training Concepts says. A child must also have the cognitive and verbal skills to express when he’s wet.

When a child shows some of these signs, a parent might consider beginning to use plastic underwear to facilitate learning and prevent leaks.
