Oops, I think I responded in the other thread at the same time Lauren split the post:
Hi, Leanne, and welcome. First, it is very common for lo's your dd's age to still get very sleepy while feeding, especially bf. The key is to find a trick, such as rubbing her hands, or undressing her, while feeding to keep her awake. Even if you have to break the latch, sit her up, and wake her, then resume feeding. This can be time consuming, but is very important. You want to make sure she gets a full feed so that she won't need a "snack" in another hour. How long is she going between feeds? Probably 2.5-3 hrs, or some variation would be good.
After you complete the feed, try to keep her awake for 15 mins or so with a walk around the house, a diaper change, or some low key activity. Then, start the 4 S's and your winddown. Lay her in her crib and give her a chance to settle. If she has trouble and begins to cry, comfort her with ssh/pat until she stops crying and falls into a deep sleep. You may need to stay by her side to do ssh/pat again if she starts to have trouble during sleep transitions. You can find much more info on this technique in the Sleep Forums if you need.
Hopefully, she'll nap for 1.5-2 hrs at a time. This would be your goal, anyway. Then, feed her 2.5-3 hrs later and start the cycle again. To help her sort her days and nights, it will be important for you to maintain this cycle and wake her for her feeds so that she does not get a big chunk of sleep in the daytime hours. She will then miss feeds, and will want to make up for that in the night.
Can you post what your day is now so that we can give you more specific advice?
