you could try moving your mattress to the floor too, so you'd have 2 mattresses on the floor right next to each other, or with a small separation, so she can feel close to you but also have her own blanket and her own space to roll around in and wouldn't necessarily wake you up with her movements. i think it's fine to nurse her back to sleep when she needs it, but maybe sometimes you could soothe her in other ways. and actually, long periods of "uninterrupted" sleep are greatly overrated. the important thing is to get enough sleep, not how long each period of sleep is. we all naturally wake up about every hour and a half or so, may roll over, then go back to sleep without even realizing we woke up. if you sleep together, your wake/sleep rhythms will usually synchronize, so that when she wakes up you will likely not be aroused from a deep sleep but rather you will also be in a phase of light sleep, and then you can both return to sleep more easily. i would encourage you also, if you are feeling sleep deprived, to go to bed when she does (including daytime naps) for a while until you catch up on your sleep. as far as the screaming goes, she needs you to help her settle, and i think nursing or other comforting measures are fine. or hopefully your husband/partner if you have one could help some of the time. what she does NOT need, especially since she is waking up screaming, is to be abandoned by you (left to cry it out) at night. and, as others have said, it really will get better as she gets older. my recollection of my daughter's first year was that she woke up every hour for that first year, which was a bit much, but she gradually slept longer stretches. and i did always sleep with her and nurse her back to sleep, until we weaned when she was 4-1/2 (by that time she was only nursing twice a day, bedtime and morning wake-up). as far as the screaming goes, you might consider whether there might be anything going on in her life that might be contributing to her fear, could even be some innocent-seeming changes in your life, overstimulation, or a previous trauma coming out in nightmares (for example, did she have a difficult birth?). you might figure something out and make some changes, or you might never know what it is, but when she wakes up screaming she really needs you to be there for her and help her calm (and not of course by shooshing her but rather by being calm yourself and really listening and empathizing with her, maybe saying something like that's so scary, i'm sorry i don't know what's wrong but i'm right here holding you). sounds like you're on the right track and are a wonderful mom!
