Hi. J.,
Our baby will be 8 months old in 10 days, and she wakes up around 3 times each night. For example, last night she went to bed at 8:30 (which is unusual, but she took a late afternoon nap), was up at 11:30, 2:30 and 5:30, and up for the day at 7:15. I bring her in to bed with me, nurse her and put her back in her crib. Sometimes she falls asleep immediately, other times she babbles and fusses, and still other times, it's more of a challenge getting her back down. I generally follow a rule with her that unless 3 hours has passed, I don't respond to her if she wakes up (unless I think something is wrong). I have made myself crazy with her sleep patterns and now I've just adopted a more relaxed approach and I deal with it...I'm not entirely convinced that when she wakes up, she's not hungry...but even if it's just some cuddling she's seeking, I don't want to deprive her of that. As long as I can still function during the day (which I can), I don't mind waking up with her. The hard part for me is when *I* can't fall back asleep...
Anyway, you're not alone---many people have suggested to me to use a pacifier, as that has worked for their babies in similar situations. Unfortunately, our baby has always rejected the pacifier and bottle, but maybe it would work for you! Also, I tried dream feeding (picking the baby up while still asleep right before I go to bed) but she woke up the same amount of times so it didn't help much.
Good luck!
