You have been going longer and longer in between naps. You don't usually get to the point of being over-tired before you pass-out, but sometimes you do! Yesterday (when this photo was taken) you were up for 3 hours and I tried everything to help you go to asleep. Finally, I rocked you in my arms and you slept for a good 20 mins until you were ready to take on the night!
P.S. You look so cute with your new pacifier :)
