I think those are fantastic ideas! I wish my husband put half as much effort into our plans!

One idea we liked was to have photos of ourselves near the crib so the baby could recognize our faces. Oh and if you do the trees, it would be really neat to have his family tree on his and your family tree on yours, with the two having branches that intersect (for you and him) and then maybe an apple or something coming off the branch to symbolize the baby. That sounds so neat!
