I purchased these for my son after being disappointed by the quality and lack of softness around the waistband of the character underwear he picked out at the box store. With my 2 year old's sensitive skin, he often gets red sores around his waist from the exposed elastic on the waistband. These are completely covered with soft cotton and have eliminated the sores. Our son can easily pull them on and off himself which aids in the potty training-empowerment :).I wasn't sure which size to get - our little guy is on the small side for his age and just got into 2T clothing at about 2.5 years. I initially purchased the 2-3T but realized after shrinking they would match the 2-3T character underwear we already had, which seemed to be getting a bit tight. So I sized up and after washing they fit him well - no concerns whatsoever about them falling down, but have plenty of stretch to grow into as well.I highly recommend these to any moms potty training, especially if their kids have sensitive skin. My son loves the assortment of designs as well and is excited to pick out a pair each morning!
