How does Lady Capulet's view of early marriage differ from her husband?

This contrast is most clearly seen in their speeches concerning Paris' request to marry Juliet. When Paris first asks, Capulet responds

My child is yet a stranger in the world,
She hath not seen the change of fourteen years;
Let two more summers wither in their pride(10)
Ere we may think her ripe to be a bride.

So he tells Paris to wait a bit, until Juliet is two years older. When Paris tells him that young girls make happy mothers, he's foreshadowing the argument that Lady Capulet will make later. Capulet does not budge, however. He retorts that women essentially lose their childhoods and happiness if they become mothers too early, by saying "And too soon marr'd are those so early made."

Lady Capulet is excited by Juliet's possible marriage. She encourages juliet to marry, essentially before it's too late.

Younger than you,
Here in Verona, ladies of esteem,
Are made already mothers. By my count,(75)
I was your mother much upon these years
That you are now a maid.
