I've used this about twice, but I no longer need it, so I'm selling it. There have been no bedwetting incidents. The size is around 110-120. It was a perfect fit for a 3-year-old. This is a pull-on waterproof sheet for children who are worried about bedwetting! It is not completely waterproof. - Perfect for active children who move around a lot in their sleep! - Pants-style design with a hem that doesn't ride up, making it easy to roll over - Elastic waistband with a drawstring opening - Waterproofing - Machine washable (use a net) - Made in China Thank you for looking.
