this sounds very familiar. I too have a 5 month old daughter who has pretty much the same exact sleeping pattern. I breastfed only for the first 6 weeks because of complications, but when i was breastfeeding, she would wake up constantly at night. after i switched to formula, she started sleeping through the night, maybe waking up once, i would feed her and she would go back to sleep. but over the last few months, she hit a couple of growth spurts, which of course made her want to eat more, so she started waking up more, then she got sick, now, she's right where your daughter is. she'll sleep 3-4 hours alone, then wake up to eat and want to be with me before she will sleep again. sometimes she won't even sleep the first stretch alone. I wish i could give you some great advice, but i can't, i haven't figured it out yet either. but i finally realized, i guess it's not so bad if she's in bed with me, it's not like she takes up that much space, and in a few months, i will do with her what i did with my son, and let her cry it out. it only took 2 nights with my son, and he has been putting himself to sleep and sleeping through the night ever since. he was about 7 months when i did that and he is 2 1/2 now. mabye you can take some comfort in knowing that your not the only one, seeing your story makes me feel better about my situation.
