I do like Daisy. But I think Daisy is a cutesy baby name, and not so great on an adult. It's a bit childish and not very grown up, imo.
I love Sophia, and am considering it for my baby...I didn't realise it was popular though, as I don't know of any around here. I may re-think.
Verity is different, and she will probaby be the only one called it in her class.
Try calling her each of the names for a couple of hours and see which you prefer.
Congratulations, she is a beauty x
