My 8.5 month old daughter also started waking at age 6 mos to nurse once in the middle of the night (after 4 hours) after sleeping for 7 hours from month 2-6. It's hard because I thought of it as a regression. I nurse her for the same exact reason. She's back to sleep in 10 mins max. It doesn't make sense to me that the AA of Pediatric book says to not nurse them at night. I know my daughter, and she will NOT go back to sleep without nursing. Why? Because she is starving! Who knows if it's a growth spurt, or she's more thirsty with the heater on (it dries out the air), or she's eating less during the day b/c she's so distractible now. The fact is she's starving or thirsty, and I am going to meet that need no matter what hour it is! Even if she does fall asleep without nursing, it would take forever to get her back to sleep and she would most likely just wake up a half hour later demanding milk! I just try my best to feed her as much as possible during the day and that helps her not wake as much.
