For my daughters second birthday I had an Easter theme party with an ice cream cake in the shape of a bunny and used small Easter baskets as grab bags and filled them with chocolate eggs, Easter grass, bunnies, etc. For games I made a giant cardboard bunny and cut out the center of the tummy for a bean bag toss-the bean bags were eggs shaped filled with soft foam chips and beans incase someone accidentally threw one at someone else. The streamers were pink , lime and pale yellow and we used Easter decorations adding of course a homemade happy birthday sign in sheet in which I painted several bunnies, chicks, eggs, etc. on a piece of bristol board with the words Happy 2nd Birthday Abbey (customize to suit) I make a sign in sheet every year for both my daughters and have all the guests (or mommys and daddys)  "sign in" so we can keep them for later and look back to see who was there. The balloons were made into bunny shapes (good luck) and in Easter colors and we also used Easter grass on tables, etc, under plates of snacks-carrots cheesies, lettuce cut small enough for young ones to nibble like bunnies--and had a headband for each guest with felt bunny ears --also face painting to look like a bunny.
