We announced last night with some photos DH took of DS. I had some pretty grand ideas of what my toddler would be willing to do picture-wise and even cookies didn't make it happen...haha oh well! We still thought they turned out pretty well.
Also, a tip to anyone doing something similar, we taped a photo of the family on the back of our US so that he would be interested in that side.
