A reusable pull-up style nappy from Sassy by Nestling.

The Sassy Straight Up Nappy Pants can pull up and push down to make nappy changes so much easier, especially for active toddlers. They sit a little lower than a standard cloth nappy and have an adjustable waistband.

These have been designed for busy toddlers and nappy changes on the go.  The 1-3 year size fits best from around 12 months old until around 3 to 4 years old and the larger 3-5 year size fits well from around 3 years old right up until they no longer need a nighttime nappy.

Please note that resuable nappy  inserts develop maximum absorbency after multiple washes, so they won't be at their most absorbent when you first buy them. We recommend washing a few times before use.
  • Adjustable sizing
  • A row of rise snaps up the front to adjust the leg holes to get the perfect fit
  • Breathable shell and athletic wicking jersey inner that quickly draws moisture away. You can slide the absorbent booster pad(s) into the pocket or lie them on the shell and secure them with the hidden snaps
  • Waterproof tummy and back panel to stop wees wetting clothing
  • New Zealand designed nappies by kiwi artists
  • Front and back opening to stuff the pull-up nappy

Includes -
  • Straight Up Toddler Pants shell
  • 1 x bamboo pad, 1 x hemp pad

FAQ'sCan you fit these nappies with an active toddler who won’t stay still?
Yes! The benefit of our Sassy Straight Up Nappy is that you can dome up the sides to the appropriate size and then pull them up like undies. Just make sure that you check that the fabric with the side snaps is flat against your little one's hips and is not bunched up. 
What are the inserts made of? There are two inserts, the larger is bamboo and cotton, and the smaller one is hemp. Natural fibres are known for their high level of absorbency and are of course better for the skin. Together they are a great combo. 
Do I need to stuff the inserts? No, due to the inserts being natural fibres they can go straight against the skin. You will find that they sit better when stuffed but many have no issues when just laying them on top and snapping them to the front of the nappy shell. If you are toilet training laying it on top may speed up the process as some children do this faster when they can feel the wetness in their nappy. 
What are the best inserts to use with my nappies? The best inserts are generally the ones that come with your nappy as they are designed to fit the best. If you are switching out inserts then look for natural fibre options are they have more absorbency like bamboo or hemp. You can mix and match the different nappy insert fibres to find a combination that works for your child or add in extra absorbency, just don’t make it too bulky or you will get leaks. Our Sassy Hemp Pad is the perfect addition to our Sassy Straight Up Nappies for extra absorbency. 

What is the difference between the insert fabrics? Bamboo - Bamboo is a natural fibre and can hold a large amount of moisture. Being a natural fibre they can be used against your baby’s skin meaning that you do not have to stuff them into a pocket. They are great for heavy wetters and for night time use. They do take a while to dry but are worth it. 

Hemp - Hemp is the thirstiest fabric used for inserts and it holds a lot of moisture. They are best paired with another fabric as they can take a bit longer to absorb moisture but they have enough absorbency to last the full night. They are a natural fibre so can go against the skin without drying it out. These inserts do take a bit longer to dry but they make up for it with how absorbent they are. 
Can I use Sassy Straight Up Nappies overnight? Yes, they are a great overnight option. The slim inserts are perfect for use overnight coupled with our hemp pad. Sit the hemp pad at the back of the nappy with the bamboo insert at the front closer to your baby’s skin for the most absorbent combination. If you are having minor leaks then you can pop a small cotton facecloth inside of the nappy to help add a bit more absorbency. 

It is best to pre-wash night nappies straight after use. This is because urine overnight is more concentrated than daytime wee and so it's best not to leave them sitting as it could result in smells over time and can deteriorate the inserts.  
Do I need to use a liner? No, this is a personal preference. Liners are fantastic if you have a little one who still soils their nappies as it makes the clean-up way easier. We recommend reusable liners over disposable liners as they are more likely to sit in your nappy and are not destined for landfill. Please note that all “flushable” liners are NOT to be flushed down the toilet as they do not break down like toilet paper and can cause blockages.
