"The best is yet to come"
"Hi Five!"
"Now no one can tell you that kidneystone pain is to males as childbearing is to females"
"Birth is the sudden opening of a window, through which you look out upon a stupendous prospect. For what has happened? A miracle. You have exchanged nothing for the possibility of everything." --William MacNeile Dixon
"Somewhere on this globe, every ten seconds, there is a woman giving birth to a child. She must be found and stopped." -- Sam Levenson
"Giving birth is like taking your lower lip and forcing it over your head." --Carol Burnett
"Now the thing about having a baby - and I can't be the first person to have noticed this - is that thereafter you have it." -- Jean Kerr
"Of all the rights of women, the greatest is to be a mother."-- Lin Yutang

All jokes aside, though...she will appreciate your thoughts and flowers no matter what you come up with to put on the card. New mommy's do tend to feel a little left out though, so it's a good idea to send HER the flowers, but the baby something its own.

I don't know what you think of this one, but I like it because you mentioned she had a long labor:
"Oh what a power is motherhood, possessing
A potent spell
All women alike
Fight fiercely for a child."
-- Euripides

Anyhow...that's what I found...I looked through some quote websites
