My daughter is almost 3 and has special needs so is not toilet trained. The quality of the product was excellent and I love that they have a built in pair of underpants so that the wetsuit material of the shorts is not directly rubbing against my daughter’s privates. She did not do any poop whilst wearing them but she did do a pee and the shorts totally contained the urine with no leaks. Best be careful with taking them off as I hadn’t realised she had done one and so when I pulled them down to take them off it all ran down her legs *lol* so I would suggest best to do it in a shower cubicle.
