Yesterday (2/4): V reached up and turned light switch off.  Too short to turn it back on.  Very proud of herself indeed!  I love that proud "I did it!" smile of hers.
Repeated "Puffffff" after me, because she wanted her Gerber veggie crunchies.
Figured out that the source of her tantrums is the fact that she wants formula during the day instead of solely before and after her night sleep - just misses the milky!
