I got this idea off the internet somewhere, but I don't remember where, so I can't give credit.
My husband and I went to lunch with parents & in-laws. We gave the mom's a gift (out of the blue) wrapped in flowery paper (to not give it away before hand). We bought photo frames from target that were ceramic with "baby" written on the bottom and little baby stuff on the edges (carriage, bottle {yuck, but they got the idea} & toys). I printed "Actual Photo To Follow November 2004" on plain paper and put it in the frame. This was a big surprise for everyone! I thought it went over well. They both have them on their desks at work now, with the text paper still in it and everything.
Good Luck!
