What are the chances? {newborn photography}

On the Sunday the 17th of July I got a surprise birthday present - My son was born. He was a week over due and even though everyone joked I don't think anyone thought he'd actually decide to arrive on my birthday!
I mean what are the chances? 
His dad describes him to everyone as a 'lovely little chap', and he really is. These photographs were taken when he was 7 days old, it's hard to believe he is 1 month old already, he has changed so much in the short time he has been born.
He has stolen the hearts of our whole family, particularly that of his big sister (although she's not too keen when he cries or getting too close to his dirty nappies).
