Nappy Overview

Trima PLUS is the BIG KID option All In One nappy by Petite Crown is designed to fit from 17-55lbs and is made for babies who have outgrown the Trima Onesize or if you start with cloth nappies later on and you know you've got a chunky monkey!

Being an all in one the Trima is the most simple of nappies to use.


To fit from 17-55 Lbs

How do I use it?

It fastens with poppers in our favourite horizontal popper position giving you a secure fit and reduced the chance of wing droop.  There are 4 rows of poppers on the front of the nappy to adjust the length as baby grows.

There is a pocket at the back for adding extra absorbency (not included) for heavy wetters.

The tummy or as we call it the "stopper" panel at the front of the nappy helps to prevent leaks by keeping inside fabric where you want it... INSIDE!

Nappy Fabric

Trima comes with two removable snap-on inserts, each made of 1 layer of bamboo cotton fabric and 2 layers of hemp cotton fabric.  The inside is lined with buttery soft bamboo cotton that provides an additional layer of absorbency. The inserts are wonderfully absorbent however they are VERY slow drying as it holds onto the washing water firmly. It can be tumble dried on low.

Lining - 70% Bamboo, 30% Cotton
Insert - 38% Cotton, 35% Bamboo, 27% Hemp

My go-to for my chunky baby
Thursday, 28 July 2022  | 

These are by far my favourite AIO nappy, they are ideal for my chunky baby. They are robust and feel high quality. They are highly absorbent (a favourite for early mornings in particular) and they fit beautifully. Highly recommend this nappy!

Customer review of free product

If you have a larger centile child who is growing out of "birth to potty"/one size nappies but is still some way off potty training the Petite Crown Trima Plus is perfect. Plenty of room and highly absorbent. Also in Petite Crown's fabulous prints. I highly recommend this nappy!

Trim but generous
Saturday, 6 June 2020  | 

My 2yr 8m old is around 33lb and growing out of BTP while being a long way off potty training. These are really trim while being generous, the inserts are really absorbent though slow drying are no slower than others we have. I love the rise poppers as many bigger options dont have this ans it allows for a trimmer fit

One of our favourites
Wednesday, 13 May 2020  | 

About a month ago I noticed the bamboozles and Baba and boo were getting snug on my 7 month old. I reached out for advice and although the nappy lady team reassured me she might slim down when she gets moving I needed to add to my stash and wanted an option with growing room. I've got a 3 year old so I'm even thinking ahead for us to be able to use these as a night nappy when she's potty trained. I am so so pleased with these, they fit so well, they last longer than the bamboozles do on her and there's loads of growing room. Even though they are a big nappy I have shortened with the poppers they don't seem any bulkier than her other nappies. We have a Julia and an orchid and they are both beautiful. I love love love these.

Great AIO nappy
Tuesday, 21 April 2020  | 

My daughter is 4 months old and I have found that I needed to use both inserts in order for it to last 3 hours. On the plus side, itís soft and comfortable against babyís bottom and itís also more roomy than some all in ones. The prints look lovely in person.
