The potty again!!

Aleaya will not go potty while we are out and about in public! For some reason she wants to come home and go potty. This is fine and dandy now, I usually will stop what I am doing and just go home but this is really going to become an inconvenience at some point..it seems like maybe she is scared of the loud flushing in the public bathrooms, not to mention the "grossness" of it all...UGHH, I really can't blame her. I guess it is a good thing she is staying home when we go to China.. I think the squatty potties might be a little much for her at this point...maybe she will get used to it soon. Anyone else have this problem with their kids???? Would love any advice...
