The inspiration for the Hundred-Acre Wood idea was a big forked branch that came loose from one of our trees a few weeks before the party. It became the doorway for Eeyore's house.
We made Pooh and Piglet's houses with a couple of big cardboard boxes, thanks to the helpful people at the Harvey Norman warehouse, then re-named the sandpit as 'the Sandy Pit where Roo Plays' and the herb garden as 'Rabbit's Vegie Patch'.
We certainly satisfied the streamer aspect of things! Just a few balloons, as blowing them up is currently making me nauseous and Dave was 2 days post-wisdom-tooth-removal. For party hats, we printed some Winnie-the-Pooh pictures and let the kids decorate with crayons & glitter.
And of course, a Winnie-the-Pooh cake! SP and I did the baking (all fructose free, including the icing!), then Dave showed that spending his days working under a microscope produces useful hand-skills for real life too. I'm very proud of his decorating.
My favourite party moment happened before the party even started. Dave and I set up the backyard while SP was having Independent Play Time in his room. When we were done, we brought him out through the front door to see the balloons on the gate and the Hundred-Acre Wood sign. Then down the side...
"Streamers!" "Eeyore's house!" "Pooh's house!" I pray I'll remember the look of wonder on his face forever.
