So, everything was still busy being transferred from my old computer to my new computer when the actual moment happened slightly over 13 hours ago at 7:33 UTC on March 14th (11:33 PM on the 13th Pacific, 3:33 AM on the 14th Eastern), but Alex is indeed now 6 months old. Half a year. Wow. The now semi-traditional monthly video was actually filmed a couple of days earlier on the 12th. But here it is. Happy half-year birthday Alex!
For those who prefer it to the embedded version, here is a direct YouTube link.
