Derek stood up really fast, so I tried to record it, but then he was already standing, so by the time I put him back down (with camera still rolling). He decided to take his sweet time. I think his foot got stuck and he wasn't sure what to do. Forward to 1.42 if you don't have time to watch it all (I know we're all in a hurry these days). That's me in the back cheering him on in Viet - in case you're like, who is that foreigner babbling in the back.
P.S. I used to think people who posted videos of their kids doing basic things was so silly - till its your kid, then its totally amaaaaazing. Tini = hypocrite.
