paddington owners: do you prefer the medium size or the baby? i didn't set up a poll, because i'm interested in hearing people's reasons for why they like one or the other. for instance, i'm 5'3" and am afraid the medium size would overwhelm me, especially when it's filled with stuff and sagging under my arm. but i'm also afraid that the baby paddington is overwhelmed by the padlock. what do you girls think? TIA for your opinions!
