Watching Lilly try to sit on a little kiddy sized chair is rather amusing.
First she looks at the chair, then she starts slowly backing towards it, turning to look at it every so often to make sure it hasn't gotten away. When her butt is pressed against the edge, she then plonks herself down.
This is generally followed with a loud "AAAAYAAEEEAAAARHA-EAAAH" directed at me because surely it's my fault that she finds herself sitting on the floor in front of her target.
At least she has a well padded, nappy covered bottom.
