I used a kit by Kat's Creations called Remember Your Firsts. Although this layout doesn't document a baby's first event, this little boy grew up living in a condo. Then the family finally moved to a real house--with a real yard, and thank goodness the yard had a real mud puddle for this little boy to play in. His very own mud puddle was very special!! Especially the first time playing in it! He had such a wonderful time.
