It's different, not common. I would be 50/50 for the name, but it will be your baby so only you can decide on what you want.
Trying to think where I heard Sonny before..
wasn't Sonny Michael Corleone's eldest brother in The Godfather?
it's an old name isn't it? everyone called my Dad Sonny...
can't really imagine a young child with it these days but sure if you both like it and it suits ur surname go for it!
Sophie Ellis-Bextor named her son Sonny didn't she? I think it's cute....
Sonny and chere! it's nice more different than i've heard in a while.
I don't like it...Sorry
i know a sonny - he's cute - mum's american though so i think that gets them away with it a bit more. i think its cute, but not sure i'd use it myself, we are too square to carry it off!
I think its cute, but DH's grandfather was called Sonny, and he left the grandmother years and years ago and is a pig so that name wont go down too well in our house!!!
But I think it's such a nice name; always think of the Paul Simon lyric in the Obvious Child :
'Sonny gets sunnier, day by day, by day by day by daaaayyyy...'
I love the name Sonny, but by the time we got preggers we had already named our dog Sunny, so it was vetoed.
And in all fairness it might have been a bit confusing for them both
