C.K.
Here's what I would have LOVED while I was pregnant:
*Help with the housework, either you do it or hire a housekeeper.
*Pampering products: herbal teas, lotions, bubble bath.
*Pregnancy books. The 2 I really liked are off the beaten path, so to speak: "Ina May's Guide to Childbirth", and "From the Hips".
*See if she wants to do a cast of her belly.
