DD3 is scared of portable potty because there is no flush and there many many $%#@^& .. inside the toilet. She also can't go in nature, could be the squatting, the no sitting part etc. So, everytime we are in places (nature) that there is no regular bathroom access, she freaks out and cries hysterically for 20-30 mins with screaming till she pees herself because she can't hold it anymore. It has happened a few times already, and we can't go hiking, fishing, camping, boating or play in river. Everytime we leave the house and before we get there, we make sure that she uses potty in regular bathroom either at home or fast food restaurants but still she needs to go some time no matter what.
Any tips?
