Suzy is learning to hold a toothbrush in her hand, get it to her mouth, and move it around ('brushing her teeth)!!
And she is also learning some beginning steps of communication.
When she wants to say "YES" she will make a shrieking sound like "a-yeah-a".
She doesn't do it consistantly yet - but I'm confidant that we are on the road to her being able to say "yes" and "no" appropriately.
This would be a VERY beneficial skill for her to master.
