Wow, there are so many posts like this around at the moment, for babies this age. I can tell you my son went through the same thing just after he turned 6 months. He was teething, going through a growth spurt, learning to sit up, crawl and pull up and so interested in the world during the day that he was just not eating enough, hence the multiple night wakings and the need to BF back to sleep (the only thing that worked!). We got through it by medicating for the teething pain, allowing him to really get in lots of practice with the crawling, etc, trying to feed him immediately after a nap in a dark, quiet room and then accepting any night-wakings as part of the deal! I too was worried about causing a bad habit, but 6-7 weeks later he settled down and was back to sleeping through the night. Hang in there!
