I tried potty training her a year ago, and it was going brilliantly until she started holding her wees in for hours on end. I've just seen another thread like this but didn't want to hijack.
I have spoken to her about it and she told me that she's afraid that wee will splash on
Her leg. She's a terrible worrier. And she gets really scared about it.
When the issue is psychological it's far harder to address. I'm not sure what may help.
