MMM, I have heard the same and we are at 7 months and DD has started some 2 am wakings - I dropped the Df one night and she wsa fine and other nights she waked for it?
Past 2 nights we have HAD he DF and also had NWS at 2am and then she is up at 4am. I DO notice that each wake is 4 hours after the last DF at 10, MW at 2 and wake for day ay 6 - I wonder if I am detting up a feeding pattern instead of a sleeping pattern?
Tonight I will do w2s and see what happens. You know I almost THINK for SURE that the DF interuppted her sleep cause last night she took 12 ounces before bed and I DF'd her 2 hours later - NOOO WAY she was really hungry. I will post back here after I tweak the issue.
Wish I could offer advice rather than simply commiserate with you. In Tracey's book Solves....she outlines dropping the Df schedule - although I was BF in the DF I was going cold turkey. If the cold turkey does not work, I will bottle feed the DF and wean as she says. We are also weaning from the last BF right now anyway.
