I love getting a small book where the "seasoned" moms can write tips on being a new mom.
Games-
Say a sentence from a popular childrens book and have the guests guess the book. Ex. "In the great green room..." Goodnight Moon
You can take the idea from a blessingway and have each guest bring a bead for the new mom that reminds them of the mom. At the shower string the beads into a necklace for the new mom.
