I'm not sure yet. Haven't checked, but I'm sure it has. Seems like it has every year. Not that it has much to do directly with my premium, but I remember when my first kid was born in 2001, it cost us almost nothing. The second cost us $600 in 2004. The third was over $1000 in 2006. I'd hate to see now if I had another one.
EDIT: It hasn't been released for 2014 yet, but looking back, my premium in 2011 was about $3500, 2012 was $4700 and no change for 2013. Same plan all along.
