Tiago spent the better part of his 4th and 5th months of life trying to perfect his crawling, from commando to traditional style. By 6 months he was simply figuring out clever ways to
circumnavigate the various roadblocks and barriers intended to keep him safe from harm.
About 3 weeks ago, having decided that he had perfectly mastered the whole crawling thing, he promptly begun his quest to crack the standing/walking code. On the night of December 1st, we decided that we urgently needed to lower his bed. On the morning of December 2nd, we found Tiago standing upright on his recently lowered mattress--close call!
During the day, Tiago climbs various objects (or people) to position himself into a standing position, and walks along furniture, baby-gates, walls, etc., until he feels confident enough to release his grip, one hand at a time, to test his balance before tumbling softly to the ground (he hates that last part).

At night, however, Tiago is not as ambitious. Lately, we have been waking to his loud cries and find him gripping the rails of his crib for dear life. Apparently, he has not mastered the soft-landing-drop, such that he can "do it in his sleep." On second thought, is he crying because he can't get down or because he can't get out?! (this video was taken while he was supposed to be napping):
