At 8 lbs 4 ozs and 21 inches, Kadeyn (Kade) Dean Arellano joined us at 12:19 this afternoon to an overjoyed mom and dad. Molly, per norm, is an absolute rockstar and doing well. Kade, albeit quietly, already seems like he wants to explore pretty much everything. Totally our boy.

If the suspension would have been upheld at least we would have had an excuse. Not a good one, but still… #USMNT #GoGoUSA #USABEL #JustOutclassed
