Wee Pants: Absorbent Undies Washing & Sizing Guide


Hi, I'm Laura the designer and creator of Wee Pants: Absorbent Undies. Here's me with the very first sample of Wee Pants back in 2017, now we sell thousands of these to families far and wide.

I want your child to love their Wee Pants while giving you the peace of mind that they collect wees on the way to your child finding the toilet. What makes Wee Pants special is the soft, absorbent bamboo layer that is easy to clean. Here are some useful answers to commonly asked questions.

Wee Pants sizing guide

What's the best size for my child?

What size pants does your child currently wear? Wee Pants are done by clothing size rather than your child's weight. Don't worry about the leg length, it's how chubby their upper thigh is that is most important as well as their torso circumference.

We have size 2 and size 3/4 Wee Pants in patterns designed by kiwi Mums. You can find them HERE

Due to them being underwear we are not able to accept returns of our Wee Pants.

If in doubt it's a good idea to order a single pair for your child to try on before you buy a bulk pack.

How do I wash Wee Pants?

To activate the absorbency before your child wears them, soak overnight in cold water. Then wash as per below.

1. Fold inside out and wash the Wee Pants in your washing machine using washing power or liquid that is free from fillers, bleach or fabric softeners. We recommend Persil washing detergent.  

2. Dry on the washing line pegging the waist band rather than the bamboo hammock. If inside, dry on a drying rack at least 1 metre away from the heater, dehumidifier or heat pump.

If they feel damp then some parents will put the bamboo on the heated towel rail with the printed material kept well away from any heat. 


How to line dry wee pants

If it is wet day, tumble dry below 40 degrees celsius

How do I use them?

Put them on your child. If your child has a wee accident:

A) Take them to finish their wees in the toilet

B) Clean the urine off their skin

C) Get them changed into clean underwear

D) Take home the Wee Pants in the wetbag and follow the steps 1-2 above as soon as possible. It is not ideal to leave Wee Pants marinading in urine for days on end.

 Can I use them for when my child is sleeping? How do I boost the absorbency? 

Here's how to use the liners and booster for extra absorbency. They are designed for light wee accidents so if your child is a heavy wetter they are better to wear a night nappy.

Why should I use Wee Pants instead of pull ups or normal undies?

Wee Pants are a great peace of mind when you are out and about. They give your child the message that you trust them and they need to consistently use the toilet. But if they have a wee accident they give you or their daycare teacher time to take them to the toilet without the wees running down their legs. 

How many do I need?

Most parents order 3. One for the bag, one on their bottom and one in the wash. If they are having lots of accidents then they will need to have more but 3 is a good starting point.

How can I avoid scrubbing poo out of undies?

Use a disposable bamboo liner. In the video above I show you how to fit it so that it catches the poo solids.

1.Tip the poo in to the loo.

2. Rinse the Wee Pants and leave them in a basket with lots of holes for ventilation. Leave them in the washing machine with the lid open until you are ready to wash.

3. When you are ready to wash put them on a 40 degree celcius wash with other soiled clothing. Leave in the bottom of the machine.

4. Then when you are ready to do other laundry fill up to a full load and wash again.

No soaking or nappy san required. 

What happens if they use them like a nappy?

I'm worried my child might not like them. What should I do?

Order a single pair to start with and write a note in the comments when you order with your child's name. That way the parcel is personally delivered to the door with their name on it. It is highly motivating!
