hi ther kal, we too are in the process of dropping the df, but we get a little off balance with it as we have both my two have been a little sick lately.
We are bf so what I have been doing is pulling back the df by a half hour or so at a time. So basically my dd would wake at say 11 for her df, so I pulled it back to 10pm, and so on when she woke, we got it back to 9pm and then all heck broke loose.
HTH
