DD10 spelled her first words (2 and 3 letter words) between 18-24 months. She was never really obsessed with spelling until very recently. Last year she was first runner up in her school-wide bee without studying the words and she went out by mis-hearing the pronouncer and correctly spelling a different word.
This year she is totally consumed. She has won her school-wide bee and keeps a notebook of words she needs to learn.
DH and I are good spellers and rarely have to look up words, but if we ever need to check a spelling we can now ask DD. :-)
