Chika is learning new things. Sometimes she forgets those skills, though. So far, she has managed to wave goodbye (albeit weakly), clap her hands, kiss one's cheek or lips, shake one's hand. She yells whenever she's excited or threatened. She screams and kicks around when somebody tries to prevent her from taking whatever interests her.
She is getting playful. She loves to point at things and people. She shrieks in delight when people are cheerful and laughing around her.
