P.B.
If you are pinching pennies, the pregnancy books are ALWAYS on the shelves of used book stores. Or even craigs list. That way you can get several for the price of one new one. (I thought I had "What to eat when you're expecting" on my shelf - Id be happy to pass it along, but alas it is not there.) That made me think of the used books etc. Mikes used books in Wakefield is a nice one (near the theatre next to Starbucks) Look on line, too!
