I am so pleased with the No Worries Undies - they are great for overnights and keep the bed and pjs dry! Much better than other 'overnight' undie products we've tried.
Hi L, I'm so happy to hear that you love the No Worries 3.0 undies and that they are working well for you, keeping everything dry. Great that they stack up against the other brands too! Thank you so much for leaving such a glowing review. 🎉
We haven't had any leaks so far using these with a 4-layer insert (or two 4-layer inserts for sleep) for our 2.75yo. He outgrew One Size Fits Most nappies before he is ready to regularly use the toilet for wee, so these have been a great alternative. Really appreciate the flexibility from having the pocket (e.g. can use with cloth nappy prefolds we already have for nights), especially as he refused to use boosters in some training pants we already had, where they just clipped in on top, against the skin (which he found uncomfortable). Also appreciate the approx leg and waist measurements being included for working out sizing, as his weight fits well within the XS range but we ended up needing M to fit comfortably around his (chunky) thighs.
Oh, that's wonderful to hear that they are working as a nappy replacement for you. So glad he's finding them comfortable and is happy to use them - that's half the battle! Thank you so much for taking the time to leave such a great review; it's truly appreciated. 🙏🏽
The Kidsaroo nappies have been a lifesaver for my long slender girl. At 114cm and only 18kg, she needed length and not width. The Kidsaroo adjust beautifully and the designs are amaaazing! Emma is so helpful. I am so pleased to have found this great business! thanks
Hi Cheryl, I was so happy to hear that the Kidsaroo nappies fit your girl perfectly and that you love the designs! Thank you for your kind words and sharing your experience; I was so happy to have been able to help.
We already had the medium in the simmers and loved them so much we committed to the Large. They're so cute and well made. Easy to clip on and off
Hi G, I'm so happy to hear you're loving the swim nappies! Thanks for trusting Kidsaroo again, and really happy you find them well made and easy to use. Enjoy!
They are made well just make sure to put inserts for overnight or they can still go through. My son likes wearing them for night
Hi Tahlia, I'm so glad to hear your son enjoys the undies! Thanks for sharing your tip about adding inserts for overnight — definitely the best way to go for most. Your support is truly appreciated!
