First I have to say how incredibly helpful this page was with my daughter and I'm so excited to be back with my son, except successfully BF this time!
My son is 2 weeks old and I've tried doing the DF the last few nights. He refuses (just like sister did). Left to his own devices he'll wake at midnight and 2:30 am to eat, take a full feed @ 15 min or so, then sleep till 6-6:30 when we start our day, assuming he goes back to sleep, still working on that part some nights. I know the book recommends trying a week to implement DF. Should i keep plugging away? It doesn't save me any sleep either way because I'm asleep by 9, so it doesn't matter to me whether I wake at 10, 11, or midnight. However it is exhausting to wake at 10 and try to do the DF every 15 min or so till 11, give up and go back to sleep, just to wake an hour later to feed him.
