My boys have big heads, too- one was always around 75th for height and weight and 90th for head, the other is 95th-100th across the board. Always good to keep track of these things, but there is a range for a reason...there is a kid for every point on the graph :) I know this isn't true, but those of us with Charlie Brown heads like to say bigger head, bigger brains!
ETA- LOL, LZ!!! So true! We have frequent head versus shirt battles, especially jammies!!
