I have not found pajamas that my 3 year old could not escape from, or at least couldn’t get at her diaper through. I have cleaned walls, beds, bedding, carpet, etc way too much. I was skeptical that she wouldn’t be able to escape these, so I only ordered one pair to start with. They worked! She tried, but couldn’t get out. I ordered a couple more pairs for her and some for my 2 year old. She doesn’t play with her diaper, but takes her pajamas off within a few minutes of being in bed and wakes up cold. She won’t be able to get these off, so hopefully she’ll sleep better. Thank you!
