New Baby Card Wording

my lil sister just had a beautiful little girl and I wanted to put some words sentimental card, but I'm stuck for ideas ... suggestions?

Have you had children? if you know the instant unconditional love you have for your new ... a love could not explain because you just have to experiance for your car ... I would perhaps put something like that out there and maybe join the club online ..:)

Tell him how you hope one day his little girl is like a wonderful woman that his mother is! and as much of a sister that her mother was to you ..

.. and tell him you're already looking forward to babysitting! =]

A little girl is an angel, sent in disguise
Hope she grows up healthy wealthy and wise.

How something like "this card comes with a Heartful of joy and love for your toddler, with all future happiness and luck wrapped in a warm embrace"
Being an aunt to your beloved daughter is a journey that I can not wait to start .......... etc. etc.

Hope this helps
