What day?

Wednesday is Water Park Day at Tessa's new school. She LOVES the water in any shape or form and really enjoyed water park day last week. This morning when she woke up I asked her "Do you know what today is?" And she said "Yes, Monday". OF course I meant it was "Water Park Day". I didn't even realize she knew the days of the week. Then she said Friday. When I told her teachers she said they had been working on days of the week.
