18 months.
Scratch that, 19 months.
She likes to sing ("Itsy Bitsy Spider").
She likes to dance (tries to run into the studio during Yaya's dance class).
Climbs everything in site. (Found her on the kitchen table, dumping salt out of the salt shaker.)
Ahead of where Yaya was in language development (which only makes sense; she's gotta be quicker to hold her own).
In short, cute as a bug....
