Hi M.,
My little one will be turning one in October. I've been thinking of doing a "sustainability" themed party (I know, sounds really exciting, eh?) but with the idea that she's been here for a year and let's keep this world a place for her to keep growing in for many years to come. My idea is that no one can bring a new gift, essentially it will be a toy/clothes/book swap. Everyone will bring toys that their kids aren't into anymore, clothes they've outgrown, and old books. Then everyone at the party can leave with some new things for their little ones as well. I haven't gotten to the real planning stage, so haven't thought through invitations or food, but I would probably do an evite to once again avoid waste that will just be thrown out. I figure there's no reason to go overboard and create a cycle of having to out-do yourself each year. Plus, they're only one... Just my two cents. Hope it's helpful!
