What do people think of the name Sid? I'm interested in opinions either way as want to ask people who are impartial My grandpa's name was Sidney and he was pretty amazing! At the mo it's the only boys name that is linked to our family that I like, but is it too old fashioned? Is it mean to call a little baby/boy Sid?! I met someone a while ago with a four year old with the same name and it was brilliant and it really suited him but just wanted to get other peoples thoughts!
