HI Linda, we just went thru dropping the df in our house. What we did to start was to pull the feed back before dd woke, so say she woke at 11pm then I would wake her at 10pm, that way she would be df and in bed before her usual df time.
Also What I found was a big help was having her on a EAEAS routine, where she rotates her milk feed and and a solid feed. But then again that is all on a preferance to what foods you are on at the moment.
With the df, I kept pulling it back if she woke up for the new time, so hopefully she would sllep that bit longer each time we adjusted her feed.
I hope that helps you hun, good luck, let me know if you need anymore ideas.
HTH
