Congratulations on your impending births.
I have 4 girls with the ages below rated thusly:
25 Worldly wise, living in London, worried about her future.
23 Still in the post-college party phase, single in the the ATL.
14 OMG! Hormones, boys and Facebook. Barely tolerates me except when she needs to draw on BOD (the Bank of Dad) but it's worse for Mom--much worse.
9 Still as sweet as can be though she tries to emulate her 14 year old sister from time to time.
I love 'em all dearly. I also know that the teen years do pass and there can be a very wonderful relationship with your daughters once they reach college age.
