Nick names for baby brother.

Meli • Engaged. 25 with a 7yo Daughter. Baby boy born Oct 17th, Napa CA
So we have a 1 year old rescue pup named Aladdin. In my family we refer to boys, mostly brothers as "Bubba" but I call Aladdin "Bubba bear" since he's the only male in the house besides hubby lol. We have a 7 year old daughter and expecting a baby boy now! I know she'll probably end up calling him bubba because that's what I call my brothers, I may even call him that. Silly thing I know. Just wondering if I should try to stop calling Aladdin bubba because I could just see it now, him come running when her hears it 😂
