hi there, i am also a mom of a 7.5 month old! my daughter is a great sleeper too, although she does not fall asleep when i am nursing her (i wish she did), but my 1st daughter did and i loved it. during the day, i would bottle feed her breast milk and so that would not put her to sleep, so she learned how to put herself to sleep during the day. at night i nursed her until she was sound asleep and then put her down. she was totally fine, don't wake her up just to get her to learn, she will learn through daytime naps and eventually when you stop nursing, she will learn to fall asleep on her own at night. I was so worried when my first daughter stopped falling asleep when i fed her.....but i put her down the first night, wide awake and sat down on the floor to see if she would cry and within 10 minutes she was dozing off. it will be fine i promise, but for now, stick with what you are doing...it is working and my theory is always "whatever works". Congratulations and best of luck!
