I have been working with Clara on learning things like shapes (she knows heart, circle, star, oval, and diamond and is hit or miss on triangle, square and rectangle. Trapezoid and hexagon are still beyond her), letters ("C" is her favorite - I wonder why? - but she will say all of them and is starting to try to identify some of them by sight - "h" and "m" seem to be the two she has the most success with), colors (yellow is still her favorite and go-to answer but she also correctly identifies pink most of the time and can also do blue, purple and sometimes green, black or white. She continues to be stymied by orange, red and brown which always default to yellow) and numbers (she will count to 10 but only if I say every number first for her to repeat even though I am positive she could do it on her own if she wanted to. I teach her using books, puzzles, toys, games, songs, an app on my phone that she likes to play with, and observations made while we are out and about (e.g., pointing out that the moon is a circle and wheels are circles and the sky is blue and that sort of stuff).
But I didn't realize that her education was sorely lacking until this morning when Paul took matters into his own hands and taught Clara how to make a proper farting sound by blowing a raspberry on her own hand. She perfected it in all of 30 seconds. Awesome.
