Hi S.,
If your baby is growing/gaining weight well, then she probably won't need to nurse during the night. It's probably more of a comfort thing for her to go back to sleep. My pediatrician told me that by 9months, a baby should be able to sleep through the night without a feeding. If you're exhausted and you want to do away with the feeding, then you may want to try sleep training her. I would highly recommend "Healthy Sleep Habits,Happy Child" by Dr. Marc Weissbluth. I actually worked for him as a nurse back in Chicago, and saw the amazing results of so many babies/kids with corrected sleep issues. He did years and years of research in the subject of sleep, and knows what he's talking about!His research backs up his methods, which I didn't find in all the other sleep books. It was THE hardest thing I did as a parent thus far, but it was the BEST thing I did, too. It wasn't just for us parents, but for my baby as well. He never seemed fully rested from waking up 3-4 times in the middle of the night, and he would suck a few times each time and just want to be held until he fell asleep. Even though I worked for the guy, I doubted myself during the first few nights and needed my husband to encourage me to hang in there. My son cried over an hour the first night (pretty hard), and then went to sleep. He cried for the next few nights, less and less, and now (he's 10 months), he whines for a second and goes right to sleep and stays asleep until the morning. He sleeps from 6:30pm-6am. I know he wakes up several times during the night as all babies/adults do (I see him moving around on the video monitor), but he knows how to put himself back to sleep by sucking his thumb instead of needing me to nurse/hold him like I used to. Now, he's so much more rested in the mornings, and he goes down easy for his naps and at bedtime. I believe that learning to fall asleep is a learned behavior and they need to be taught it. Some babies get it quickly, but some others are more difficult. But if you're not comfortable with letting your baby cry, then I don't think you should be pressured to do this. It was hard for me..but I knew that I always attended to him immediately throughout the day and therefore he is secure and loved. Just as I can't let his crying stop me from changing his poopy diaper (which my son hates), he'd rather play and not sleep, so he fights it and cries. But you will be so happy when your baby knows how to fall asleep and stay asleep on his/her own. Hope this helps!
