Help! My nappies are leaking

If you are getting leaks it usually comes down to either Absorbency OR Fit. Keep in mind that all our nappies, training pants & inserts take 10-12 washes to reach their peak absorbency. The natural fibres need to be fluffed up to allow the moisture in, so if you they haven’t been washed this many times, be patient and just change bub a little more frequently or add in an extra booster until they are at max. capacity.


A cloth nappy should last you 2 hours – 4 hours depending on the nappy style & your baby. The AIO is the least absorbent, whereas the Fitted Nappies are almost triple the volume so you will get varying capacity different across all our nappy styles. The Night Nappy holds even more and can last 10-14 hours. If the nappy/inserts are fully wet when you are getting leaks, then it means you need to either change more often or add another booster. Once the core absorbent layers are full, then there is no where else for more liquid to go except out of the nappy…. hence the leaks. You can use anything absorbent to boost your nappies (clean cotton face washers, old muslin wraps or something like these Magicall Inserts). I like to fold my Magicall Inserts in half, then position in the main wet zone.

If your inserts are only half wet or mainly concentrated in the front/middle or back, then just adjust your insert folding so the majority of the layers are in this zone or add an extra booster to this area.


Ensuring you have a good firm fit on your baby is important to preventing leaks. You want to be able to run a finger under the leg/waist elastics, but not have it loose enough the wee will just run out the side and not too tight.

– As your baby moves around, if you notice the leg area getting saggy then next time pull the nappy up higher around the waist and secure firmer.

– If using a one-size adjustable nappy style, then if you find the crotch area gapping, then adjust the nappy size down to the next smallest size so you get a firmer fit.

– The nappy should be even around the waist – front and back waist should be the same height around the tummy.

– Ensure that there is no liners/inserts poking out of the nappy, otherwise the wetness will wick across & you will get wet clothes. Make sure everything is tucked inside the PUL layer to avoid leaks.

    Hey team. Yeah be been using the AIO nappies for a few months now and am loving them soooooo much. However, my daughter now sleeps on her tummy and I’ve noticed her clothing around her tummy area is wet after her day naps and her nappy is saturated. I feel like her wee is missing the inserts.
    Is there a way I can prevent this from happening?
    Thank you in advance.

      Hi Kerry, As your little one grows, so too does the size of their wees so if you’re finding the AIOS aren’t quite enough for day times, then your best bet is to try boosting them as follows. Grab any type of insert/booster (bamboo, multi layered is best), and fold into two or three. Slip that inside the pocket in the front of the pocket where her main wet area will be when she is asleep on her tummy. The wee wont be missing the inserts, there simply isn’t enough absorbency especially if her body weight is ontop of the nappy (ie compression leaks) so try adding more absorbency. Also keep in mind the AIO is the least absorbent of all nappy styles, so it isnt designed to hold as much liquid as something like a Fitted Nappy for example.

    I have had my nappies for two years and they are now being used for my second child. I’ve noticed they have small holes forming on the elastic around the leg area. I have decreased the spin cycle on my washing machine but this has still happened. Is this normal wear and tear?

      Hi Penny, Small holes in bamboo fabric usually indicate the bacteria which is acidic isn’t being washed out properly, so the cause is typically something in your wash routine that needs tweaking to prevent it happening any further. Acidic wee and a weak detergent or cold wash or length of cycle will may cause problems like this after a long period of time. If a wash routine is correct, then not it will not happen. More than happy to help trouble shoot your wash routine please please get in touch. We would recommend a strip & sanitise to remove the bacteria build up, then tweaking your wash routine from there.

    I have read through all of your basic washing advice pages and that is the routine we’ve been using. I have a couple of more ‘advanced’ washing questions.

    We’ve been using Magicall Ai2s for our now 12 weeker using the Rockin Green brand Platinum detergent (one scoop per load as per packet directions). So far the nappies and inserts have been coming up really well. Provided we keep up a good wash routine, is it possible we won’t need to do a ‘strip and sanitise’ routine ever? Do you have any advice about intermittently washing with a stronger detergent or keep doing what we’re doing provided no stains or smells?

    Also, I’ve been using a hanging XL wet bag with zip open as our ‘dry pail’ and wash every 1-2 days. Do you think this is a reasonable long-term set-up Toltec should we use something with greater airflow (such as a basket)?

      HI Maree, Great questions … Yes if your wash routine is perfect and you have clean, fresh smelling nappies then there will be no need to ever do a strip & sanitise. You really only need to do a S & S if you start to get stinky nappies or if buying second hand, or bub develops a fungal infection.
      In terms of ongoing washing advice, so long as you’re washing with a detergent that has enzymes which really give a deep clean (like RG) AND your doing a long, 60 degree wash then you shouldnt change a thing. Stains you can use a pre-wash spray no problems.
      Re the XL Wetbag – remember it has tiny holes so does breath well – its not as breathable as a basket, but it still has airflow. If youre in a hotter/humid area then a basket might be a better idea, but for the most part the XL wetbag is totally fine!

    Hi 🙂 We’ve been using the new born all in one nappy on bub since 2.5 weeks and have had zero leaks with them up until the past few days where we’re getting them consistently at each change. He’s 7 weeks now. They do still fit him well, so I’m wondering if he’s feeding more and wetting them more.

    Is there a way to add more absorbency so I can still get a few more weeks out of them? He’s 4.3kg 🙂 and we do use the NB booster it came with.

    Thank you!

      HI Chantal, You can add anything else absorbent to give you a little more absorption inside the pocket – anything cotton, bamboo is fine … Like a face washer for example makes the perfect little booster. Just fold into a rectangle and add in.

    I’m having absorbency problems with the All in Two with my 22 month old boy. Granted they may have not reached full absorbency yet due to still being quite new. What would be the best configuration for the inserts?
    I put the smaller booster inside the pocket and then the long snake insert sits on top of the pocket closest to the skin, I fold towards the front for extra layers. We get leaks between the legs towards the front.
    Would appreciate any tips please.

      Hello! So yes firstly, they do take 10-12 washes to reach maximum absorbency so that will be part of the problem so keep washing them. I would recommend trying both inserts inside the pocket, and also both on top of the pocket. Every babys shape is different and what works for some, might not work for others so its a little bit of trial and error to see what works best for you. For a boy, ensure you’re folding the long insert into three at the front to give you the move absorbency in the wet zone. If the inserts are fully wet when you’re getting leaks, then it probably means its just the absorbency isnt at capacity yet… If the inserts are only half wet, then it means its usually a fit issues so try adjusting the inserts as above. If you’re not sure on the fit just send us an email with some pics of the nappy when first on bub, then after 2 hours so we can help.

        Thank you for the reply. We had another leak this afternoon. The inserts were completely saturated from top to bottom and back to front so definitely must be that the absorbency hasn’t reached full capacity. I will keep washing them.

    Hi what’s the difference between the all in one and the all in two?

    • AZSXDC@123 August 21, 2020 at 1:54 pm - Reply

      Hi Amanda, Great question!
      The All in One is a Sized Nappy, where as the All in Two is one-size so you adjust the sizing with the buttons on the front.
      THe All-In-One is a one piece nappy so everything is connected – when the nappy is wet/soiled the whole thing needs to be washed, whereas the All in Two is a two piece system so you can simply replace the absorbent insert with a new one, and reuse the shell.
      The All in One is the easiest style, whereas the All in Two is a little fiddlier to get used to.
      All in Two is a more slightly absorbent nappy 🙂

    I accidentally washed my all in one nappies with fabric softener have I ruined my nappies. Dam baby brain.

    • AZSXDC@123 May 28, 2020 at 1:23 pm - Reply

      Hi Juanita, No the fabric softener will rinse out anyway so just run them through a few normal wash cycles (good detergent, 40-60 degrees) and it will wash out after a few washes!
