When I dropped the girls off at daycare this morning, their teacher wanted to show me something. Apparently they've been discussing morse code and the symbols for each of the letters. During free time, Lily spelled out her name correctly in morse code from memory.
Now, she's probably since forgotten it, but I'm glad she was interested enough to work on it in free time too.
Madeleine also talked to me about it, but just SOS specifically. I guess I need to brush up.
