I really love the gumnut baby suggestion - too cute.

I have to share something about aussie costumes though. Totally inappropriate (or maybe not) for your DD to wear as a bub BUT - my younger sister was in a school play as a kid with an Australian theme and she played the part of - wait for it - the Aussie Meat Pie! I'm laughing as I type now. My Poppy made her this great big costume shaped with flexible pipe for the frame and covered in brown mesh that was the actual shape of a meat pie. She wore brown tights and popped the pie frame over her head. BAHAHAHA she looked hilarious - and yes we have video footage. GOLD. Thanks for reading my little side story!
