Best bundle ever

I was on the fence about preflat. Saw Mimi’s video with her son and thought it looked so comfy. This is the best bundle ever. Not too much to make you question yourself if you regret it. It made me order more after. Buzz is my absolute favorite print 😍 I bought two preflat in that print and it sold out 😭 I wish I got more of them. My second favorite print from my order is burnside. The combination of wool on the pre flats will be my go to now. I haven’t gone for my 2.0s after my preflat a arrived. Bub is 13 months. I wish I had gotten these much much sooner.

Absolutely love this option for our newborn

So easy to get a great fit on our tiny newborn! They fit soo much better than the newborn size disposable nappies. Such a great option for the newborn stage.

I never thought I would be one for preflats, they looked way too difficult but after trialling another type and having leaks I thought I would give them a go. Night 1, I could do with some practice but they were very easy to fold with the new elastics and we had NO LEAKS with both my baby and toddler (with inserts and wipeable cover). In love. Will be purchasing more when they're back in stock.

Great size to fit over the bulk of a night nappy. Worked perfectly on my 6mo over a preflat and inserts, she completely wet the nappy but no leaks! Did leave some nasty red marks on my toddler, however it was my first time using these and can definitely see some improvement in my fit (plus he's a big boy, maybe a wool cover will suit him better down the track)

Very cute

My favourite preflats. Works great with a snappi! 👏The elastics help give a good leg seal even when using inserts. They do limit some of the folds you can do though.
Pooh bear prints are so sweet too!

Absolutely gorgeous!

I’ve tried other brands but converted my whole stash to Mimi and Co as I’ve found them to be far superior. Preflats seemed scary at first but they’re actually really easy! I recommend practicing some folds before trying them on a wiggly baby. And look at this cute print, how could you not!?

Exactly what I was looking for

I am new to the cloth Nappy world and decided to bring my journey with Mimi &co. I can 100% vouche that this was a brilliant idea. Especially these preflats. I love them 😍, especially the stretchy fabric , which allows for me to get the most out of them, not just for my newborn. The prints are amazing, I currently have the kanga, emu, echidna, Lacey, the buzzy bees and earth. Without a doubt my favourite prints. I feel very secure with my preflats and their absorbency, they are the perfect combination with PUL shells 👏 definitely start or complete your cloth Nappy experience with these preflats.

Favourites for 3 month old

Have my second child in cloth and felt adventurous to try something new and added a few of the organic preflats to my existing nappies. Best decision as I reach for them first. Luckily they dry fast so I never have to wait too long to be able to use them again.

Such cute prints!

My mother-in-law bought us a starter bundle in 2024, but the baby she bought them for never came home. Our little boy was born in February 2026 and I got to use our Mimi and Co for the first time! My husband and I loved using the preflats on him, so we ordered some more.

The new prints are adorable and they still work really well, but I do find that the older preflats from 2024 are thicker and easier to use than these newer ones. They feel more substantial and are a bit easier to fold than the new version, though I haven't noticed any difference in absorbency levels.

Our little boy is 4 months now and the preflats are brilliant with a hemp booster folded inside. We initially used them as night nappies, but I love using them during the day now that he needs more absorbency at night. He's around 6kg now and so we'll hopefully get heaps more use before he hits the 10kg limit.

The best nappies

We have used the organic cotton pre flats since our baby was two weeks old. We have just sized up so we can keep using these nappies as our bubs is now 5 months. We find them so easy to use, they are amazing on our bubs skin, we haven’t had any issues with nappy rash despite initially having poops every two hours. Love that they are made from organic cotton, and we can use pads for extra absorption that aren’t on the skin. They are still all sparkling white and dry really quickly. 10/10!!

Simple easy to use nappies!

Nice snug pre flats. Fun prints to go with our collection of cotton diapers.

Our little boy is 3.5 months now and the preflats are brilliant with a hemp booster folded in, plus the stay-dry liner on top. We initially used them as night nappies, but they're brilliant during the day now that he needs more absorbency at night.

Trim and Clever Design.

I love these Newborn Preflats. I have been using them since 8 weeks old (4.5kg), during the day, for 2 months (now 6kg). The elastic legs create a snug fit around the legs, containing everything. It is a very trim nappy even when used with a wool cover. It is also very absorbent on its own.

I have started using at night as well. I just add extra absorbency between the folds with a wool cover over top and I have the confidence that it will last through the night (if we get that far). I think my baby will fit them for a few more months then I’ll move to the OSFM Preflats. Clever design.

Awesome product

Communication was excellent and product is wonderful. I didn’t fully understand how to use the preflats but once I got the fact that they still need the waterproof outer layer it all made sense.

We heart these preflats

I tend to use a mix of preflats and 2.0 nappies and it’s probably partly because we love these preflats so much! You can pretty much use anything in terms of inserts and it works. Bump the absorbency up and hey presto you have a night nappy!
I have some printed preflats too but I do love the white ones because I can throw them into a prewash with bleach and they don’t fade and just come out beautifully.
I also just love how comfy they seem on bubs

Pre-flats

Using with wool cover as night nappy due to previous nappy constantly leaking. These along with snake and booster have stopped all leaks so very happy. They are a little tricky to get on until you get used to them.
