Submissive/excited peeing isn't a matter of housetraining. It's about the fact that she basically loses control of her bladder when she's excited or nervous/scared. I have a dog, 2.5 years old, who pees EVERY darn time he sees my dad. Keep in mind, he LOVES my dad, and when we go visit my folks he follows my dad around, and sits on his lap and loves attention from my dad. But, when we first get there, he pees the minute he sees my dad. So, we always make sure that we have them greet each other outside, so there's no mess inside.
Submissive peeing doesn't have to be because she's scared. It could be that she's excited to see your mom, or just unsure about her, if she doesn't visit often she may not remember who she is. OR, she's peeing from being submissive: she's a bit nervous and is showing she is no threat to your mother.
Usually, people say they do grow out of it. Harper doesn't do it anymore, to anyone except my dad.
