The regular baby is more practical for me because my urethra stays lined up with the cage opening pretty well so I can pee at a urinal. That would mostly be a disaster in the narrow. That said, I'm back in the narrow now because I love how small it is and just dealing with it 😅

I waffle between the baby and the baby narrow. The thing to know is that it's not just shorter, it's also quite a bit narrower. Fitting it around your head if it's generally as girthy as pictured might be a challenge.
