Have not used them yet. Quality seems good, feel nice and soft.
Other reviewers have mentioned that they run small, so I wasn't sure what size to buy, and regret not getting the large. My daughter is 2yr old, 14kg, and her hips (narrower than her pot-belly waist!) are 51cm. I wish I'd been guided by the waist measurement and gotten the large, even though the size guide puts it way beyond her weight and age, because the undies are a bit tight on her waist. Hopefully not too tight to be comfortable when we get properly into potty training.
