Yeah, that's a pretty nice store. I have bought some things on sale there, though it is a little expensive for my taste. There is an Old Navy maternity section in the ON on Cedar Hills Blvd. I also bought a lot of stuff at Motherhood Maternity but they don't handle returns very well and they hassle you for your name and address and sell it so you get all kinds of junk mail. But I do like their clothes. There's also a Motherhood Maternity outlet in Woodburn.
Have fun shopping!
