Letter learning....

Isla's been VERY interested in letters lately and Super Why! is her new favorite show.  O is her favorite letter--she points it out on signs, boxes, papers....  And she knows that the 2 letters that make the /ew/ (ok, I don't really know my phonetic expressions) sound in "food" are OO (thanks Super Why!).  She also knows t, and gets e and i right most of the time.  Super Why uses upper and lower case letters though and every time she sees l, she says I.  Smart girl, but I hope it doesn't confuse her.  I'm pretty impressed with my girl!
