Hi Jacki - I had been thinking of trying the same thing with Molly...eliminating the DF.
When you say she woke up at 2-3, then again at 5:30, were you feeding her both times? Is she bottle or breast fed?
We have Molly on the 4 hour EASY, she is going down at 7 pm (awake at 6:30 or 7 am for the day) and I DF her at 10. She takes 4 bottles during the day, 6-8 oz each time, but the DF she only takes 4 oz.
She also wakes a few times during the night but I don't feed her, I just go in and resettle her (takes a minute or two) and she goes off to sleep again so I know she isn't hungry.
I too am wondering how it will go if I drop the DF...anyone else out there done it and had a good experience??
