My 22 month old daughter strips every day at naptime...all her clothes and her diaper, but she never pees or poops at naptime. We used to duct tape her diaper too, but she started managing to get that off too, so I don't bother. Thankfully, she stays dry at naps and night. Fingers crossed I never have to go through what you did! I did catch a daycare child once with one tab off the diaper...full of poop...thankfully I checked as she has a hard time going to sleep and often poops! I think it is oh so much worse when it's not your own child!
