I noticed today that you have the 2010 Due Date boards divided into Spring/Summer/Fall/Winter instead of by month. I was wondering why not do that for 2011 and even 2012.
I was due spring 2012 and I know we usually just lumped together anyway. Plus, I think as far back as 2012 that our babies are old enough that the month doesn't matter so much anymore since the range of when kids hit milestones and have issues is wider. It might declutter your due date forum listing a bit to do that.
Just an idea!
