I held a baby shower about six months ago and classic pooh was available on lots of things. Look in the baby shower section of the bigger craft stores (michael's, etc) there were invitations, decorations all sorts of things.
"Hunny" is the only food I associate with the hundred acre wood gang. Pooh and friends was originally a British tale, wasn't it? Maybe English trifle? instead of cake? Some English chocolates. Make it a tea party - finger sandwiches, scones, etc?
If you have a local 'paint your own ceramics' place (they were popular here for a while, we only have one left now) they might have a mold that looks like a hunnypot that you could paint/personalize. Depending on how many you want the money and effort might be too much, though.
I just googled - classic winnie pooh baby shower - and found tons of stuff. If you start there and dig around you might get some more ideas.
Good luck! I had a ball planning the one I did but it's a lot of work.
