You have to pay very close attention, because she isn't very clear, but it's there. Mixed about forty-sixty with babble.
Also, she's about the most obliging toddler I've met. Any request she understands (that doesn't involve walking away from a cartoon, mind you, but that's almost too much to ask for at this stage), she will happily do.
Unless she's teasing you, in which case she may run around in circles and squeak for a while first.
