We had another joint birthday party for the girls this year. It's definitely sooo much easier to plan one party than two, but the girls did try to make things a little more challenging for us this year by requesting specific different themes from one another! Lucy wanted a Peppa Pig party (her fave - she goes around snorting and saying things like "post" and "swimming costume"), and Violet wanted a mermaid party with a very specific pink cake with strawberries and a mermaid on it.
Not to be deterred from my one party and done plan, we managed to make it work - we basically just split the table in half and had Lucy's side and Violet's side. We didn't want to spend a lot, so we went with a basic pack of balloons along with the gold number balloons that we do every year, I painted a backdrop on some butcher paper, made table runners out of gift wrap, and made the (slightly lumpy) cakes myself. For the Peppa Pig theme we found some cute printable cupcake wrappers and toppers on Etsy which we cut and assembled. For the mermaid theme it was an Ariel doll and Pinterest to the rescue. I found some easy looking oyster/pearl cookies, bought some rock candy at the local party store, and plopped Violet's Ariel doll on top of the pink-by-her-request cake. All of the other decorations we re-used from previous parties - yippee!
Luckily the girls were thrilled with everything and the only squabble was who got to each which Peppa Pig character :) I call that a success!
Happy birthday girls - love you to the moon and back! xo, Your Mama
