We just finished up our 8 day birthday marathon at our house, with our oldest turning 8, our second oldest turning 6 and Mom turning 24. Again. In the winter, your options are limited for birthday parties and entertainment, especially if you can’t afford skiing, snowboarding, snowmobiling and the like. This year for our six year old’s birthday outing we headed to Jump On It, in Lindon, Utah. This turned out to be a lot of fun. We brought our four kids plus two of the neighbors and we all loved it.
