My dd is 9 weeks old and right now she has her last feed about 7-7:30 and is asleep between 8-8:30 (I am aiming for 7:30, but it is usually later) and sleeps until between 3:30-5:30 eats and back to sleep for 3-4 hours. So I am thinking of starting DF to see if this will help her sleep through until 7 (or at least 6) because I don't mind this, but I am going back to work Sat and I don't get home until between 10pm and midnight. So if I want to do DF would 10 be to early if she ate at 7:30 because the nights I'm off I am so tired I want to get to bed as early as I can because I am so tired (I have 6 & 4 year old also). Also does DF only work if you do it every night? How long should it take to get results? My dd#2 slept 6:30-6:30 by 3 months (also ebf) so I know it is possible to go that long between feeds by that age, but I also know every baby is different. She normally eats 6 times/day plus the nw, but the other day only ate 5 times and still woke the same time. I do try to get a cluster feed in the evening, but sometimes is only 1 hour apart because naps are off during the day and she doesn't eat very much at those times.
