I just updated mine too! You all inspired me. I used Kristin's Baby On Board kit and I'm thinking I'll leave it up until this baby is born. Sarah, I'm like you, I like to change often. For awhile I changed every month and then I kind of did a season theme. It's just kind of fun. But I agree, that it can be time consuming to get everything with the html just right.
