These are good for potty training but not to leave on for night time. They do not fit tightly enough for night time/bedtime. My grandbaby woke up with his clothes and blankets wet. I bought these to use instead of diapers because he is potty trained and does well during the day. I bought these so he could go to the potty at night like a big boy and have protection, in case he did not wake up or didn't quite make it. So, for now, we use the seventh generation diapers, which work great!
