Scarlett's 4th Birthday

Scarlett is turning 4 in December.  This is the first year that I actually have no idea what we're going to do for her birthday.  I don't know if we're having a party for her, or will just take her to do something fun.  You might say well it's only August, you have time! If you know me, you know that I like to plan in advance.  I usually have the party theme planned out and I start to buy decorations in about a month or so.  I'm completely out of ideas this year!

For Scarlett's birthday last year we had a pizza themed party at California Pizza Kitchen.  Part of my problem is that my house is not very large, so I can't have too many families over at once.  A party at a venue like a trampoline place is about $350-400 for 10 kids and doesn't include decorations, food, or cake.  As you can see, it's pricey.  

For Scarlett's 2nd birthday, we had a party in my house but it was really tight.  I am not sure if I want to just have a few of Scarlett's friend's over, or if we want to just take her to do something special in New York City since we don't live far.

Hopefully I can figure out a plan soon.  December is not as far away as you think! What did you do for your child's 4th birthday?
