Brushing her teeth. If she spots her toothbrush she says “teeth! teeth!” … then she stands on the step as though it actually gets her much closer to the sink. It’s part actual brushing & part shaking her head from side to side and saying “ch ch ch ch” to really give it the brushing sound effect. She finishes with a pretend spit which involves no actual spitting, but just a lift up to the sink where she leans over and makes the sound “pttt” then proudly smiles because she’s really got the hang of this teeth brushing thing.
