I really like the Wonderful Moments Photopolymer stamp set for both the images and for the sentiments.
I stamp the expectant mother image several times then colored them with Stampin' Blends. Here are two of the finished cards.
DSP is Garden Impressions (still on sale through tomorrow)
DSP is Twinkle Twinkle and is also part of the Buy 3 get 1 free sale.
