There are many differing opinions as to whether the baby, or medium paddy satchel can fit on the shoulder.
For me personally, i can fit the medium paddy over my shoulder, very comfortably - but not when wearing a huge coat.
So it's *primarily* a hand held, or crook of arm bag in the winter.
Summer, no problem!
The baby paddy is smaller than the medium, so i would think this problem would only be worse! However, some say they can wear it on the shoulder for brief periods.
