My 3.5yo girl has been potty trained a little after turning 3, using the toddler potty and big toilet alternately which started about 4mo ago, never leaving her side when she uses the big toilet. She has always covered her ears with certain loud noises but flushing the toilet has never ever bothered her before. When she started covering her ears upon entering the bathroom, I didn't think anything of it, but in the last 2 months her behavior changed from just covering her ears, to telling me (her dad, my mom - 2 other households) upon entering the bathroom not to flush, to crying and anxious. This is especially tough when we are out using public restrooms. I have a portable potty in the car which I make every attempt to use when we are out and about but when we are too far from the car, I intentionally pick to use the biggest stall so that (after the crying and pleading and finally peeing) she can be at one end of the stall while i flush the toilet, which use to work but not anymore. I do a lot of reassuring, encouraging, holder her tightly before, during, and after the whole thing. When we come out of the bathroom, we are both emotionally overwhelmed and tired. I keep a calm composure while I continue to reassure and help calm her down while deep inside I want to cry along with her 'cause I feel so guilty for what I just put her thru and frustrated for not knowing what to do to make all these better for her. I have talked to her dad and my mom and I've tried to talk to my daughter, still I cant figure out what started this fear/anxiety/change in behavior. I feel stuck and I have no idea what to do. I am desperate for any insights, input, suggestions, and I appreciate any stories or experiences anyone might want to share so that I don't feel so alone. Thanks a lot!
