I have a kitchen island that on occasion I will have Gillian sit on to tell me about her day. It is the perfect height so I can look her in the eye as we are talking. 

This week while I was making dinner, I turned around and there she was sitting on the island. 

She has figured out how to climb up and down on the island. She is very proud of her accomplishment and anytime I am in the kitchen she sits on the island.
