I have now ordered 2 packs of these, at 2 different times. I have ordered so many brands of potty training panties and covers on this potty journey for my toddler and these are by far the BEST WATERPROOF covers we've had. My child uses these along with a potty training panty underneath; these covers go over it. If she wears this cover by itself it's not really comfortable for her; the material makes her sweaty and sticks to her skin. But as a cover, it is simply amazing. She's still learning when to go potty so before these, there was pee everywhere because it would just leak out before she could make it to the potty. With these, it contains the pee in the cover! She would have an accident and there was no more leaking down her legs and puddles on the floor or as a trail as she ran or walked to the potty. I literally can't count the amount of times that we can see or feel she had a potty accident but it stays contained in the cover. She can make her way to the potty and nothing comes out on the floor until you take off the cover—then it's like you opened the flood gates. There was only one time the cover didn't prevent a leak, which was when she was sleeping on her tummy and the leak came through the waistband area (not common). These are worth every single penny for the amount of messes it contains (works just as well for poop). I'm actually thinking of ordering 1 more set because I have 4 of these potty covers as extras at her daycare and 4 here at home and it would be good to have some more. My only complaint would be (1) that the sewing on the elastic waistband comes loose in the same place on about 4 out of 8 of them —though luckily it's not on the legs so it doesn't impact its ability to stop accidents from getting all over, and (2) I wish there was a larger bulk pack at a discounted price because 4 covers is just not enough when you can go through multiple a day. The patterns are cute and colors are vibrant; no fading has occurred after multiple washes. I ordered size 4 for my 3 year old and she's tall for her age (90th percentile) and average weight but these do run big. But it's ok since she does wear the panty underneath and she seems comfortable in it. Overall, I'm super happy with these and I highly recommend them. If only I'd known about these first—it would've saved me lots of money. You won't be disappointed with these truly waterproof panty covers.
