Hi there Nomi - sorry you're having a rough time of it! Do you have Tracy's book? You might find it helpful to read it - it explains about routine and the importance of getting full feeds and good sleeps during the day. But here are a few things to think about:
Babywhispering is all about EASY - that's a flexibe routine based on having your baby follow the pattern: Eat, Activity, Sleep, and then time for You!. So you're aiming to have some play time after she eats, so she's not being fed to sleep. At 6 months, for most breastfed babies, the routine from start to finish will be about 4 hrs (give or take - could be just 3 hours or more than 4). So if you start the day by feeding her at 8am, then she should be ready for another breastfeed (after having had some play time and a good nap), by about 12pm - you see what I mean?
You also want to make sure that she's getting full breastfeeds during the day, so she's not as hungry for the breast at night. That's part of why it's good to have a routine, so you're not just feeding her snacks all day. Try to keep the distraction minimal when she breastfeeds to help her eat more at one sitting and get the fatty milk at the end of the feed.
Then comes naps. If she's only having a bunch of 30 min naps all day, she might be getting overtired by the time bedtime comes. If she's overtired, she may not sleep as well at night and she might be harder to put down. Tracy's book talks about extending naps, but there are also some great links on the nap forum. At 6 months, most babies have 2 long naps (around 1.5 hrs or so) and a shorter nap later in the day (30-45 min).
For bedtime, it's really important to have a routine. If she's playing, then all of a sudden you notice she's rubbing her eyes and you try to put her down, she'll fight you, and she won't be as relaxed to have a good night's sleep. Better to choose a bedtime that works for you and your family ahead of time and stick to it. Most people here tend to aim at a bedtime around 7 or 8pm...I notice yours is much later - is that what works for you though?
Once you choose a bedtime for her, start a wind-down about an hour in advance. Quiet play...bath, massage, reading a book, a breastfeed... have it all end at bedtime, so that you can put her down even BEFORE she starts rubbing her eyes.
Finally, you have to decide what you want to do about nightwakings. Do you want to keep feeding her everytime she wakes up? She may well need to be breastfed once overnight at this age. But remember, if you feed her close to her morning wakeup time, she won't be hungry when she wakes and you want to try feeding her fairly soon after she wakes up... Whatever you do, you need to be consistent, so that she will know what to expect when she wakes.
I hope that helps a bit! Good luck and let me know if you have more questions.
