Note I am the happy aunt to be and not the mother (so you can all be brutally honest!). My sister had asked me to canvas opinions and the fastest/easiest way I know is mumsnet. 
Anyway...
My lovely sister is having her first daughter and she has firmly settled on the name Daisy, but her DH is really worried that is sounds too cutesy and is only suitable for a little girl.
Our gran suggested Margaret as Daisy is apparently the official nickname for it.
Is this a thing any more? Is it too unusual?
Basically the child would be known as Daisy and use Daisy as her name but would have Margaret on the birth certificate and as an option for later in life.
What does everyone think?
