Lilian usually has one or two long periods per day where she plays by herself, puttering around. Moving stuffed animals, creating a tent, reading books, whatever. I'm usually not paying much attention to what she's doing and I often find clues later in the day, like this one:
This little image brought a big smile to my face. These two turtles are from 2 different "play sets" and I don't think they've ever been in the same room together. It melted me to think of her helping the baby discover it's mama. And I know that she put them together like that so that they could "kiss". I just wish I had been present for the little girl's narrative!
