I love a great zoo or safari theme (me and my fiance' have a zoo pass even ;o) so why not switch it up and go pastel and use it as a baby shower or 1st birthday theme?
I thought this would be the perfect invite to get the ball rolling! Source
These little favor bags personalized with the birth date and name would be so sweet! Source
Elephants look familiar? They were in my Ikea shopping Sat post! She attached them on top of clear favor boxes and filled with animal crackers... how cute do they look!?! Source found via partyperfectblog
You could give out little baby elephant soaps as favors or stash them in the favor bags above! Put a pile in a basket in the bathroom at the party to carry the theme throughout the party space! Source
A diaper, washcloth or blanket "cake" is always a great centerpiece to the party! Source
Why not get a matching brag book, or guest book that guests can write sweet messages to the new baby in. Source
Ending on a sweet note, you could add animal faces to onesies and rattle cookies! Source
