Our 6 year old son is on the autism spectrum and has ADHD. Potty training took a long time and was difficult but we’ve been mostly there for about a year. That being said, night time is a different story. I think it’s going to take another year to fully get night time potty trained as well. In the mean time, our big boy doesn’t fit in the largest diapers anymore so these have been the perfect next step. He pees in them every night and they do a good job of keeping him, his PJ’s and the bed dry. They’re not as effective as a diaper for a lot of urine but for the average nightly output they do a great job and they fit him really well. Our son weighs about 52 pounds and the S-M size fits great. I have these on my Subscribe and Save list and they’re definitely cheaper than buying at Walmart that way. Hope this helps someone else!
