Frog

Yesterday, I noticed Sasha was hopping around the house saying "Ribbit! Ribbit!". She's been doing that increasingly lately. I joked with her and asked her if she was a frog. She looked at me funny, thought a second, then said "uh-huh".
I didn't think much of it until a little later. I called to Sasha, by her name, as I always seem to be doing lately. She sternly responded by patting herself on the chest and saying, "NO! Frog!".
She kept this up all day. She gets upset with us if we call her Sasha. She is now Frog.
Cassie finds this very amusing.
There was a break for an hour yesterday evening, when Sasha was playing with her toy doctor set. She no longer responded to Frog nor Sasha. "No! I Doctor!" she corrected. But once she was done with her doctor set, she was back to Frog.

This is a first for Sasha. Pretend play? She's always played with her dolls in a pretend play sort of manner. She mothers them. But I think that's a bit different. That was more like mimicking than pretending. I suppose now that I think of it, Sasha first started giving her dolls voices a week or two ago.
Something interesting is happening in her little head.
