If I were sleeping, I'd be dreaming of sleep!

My baby girl is NOT the greatest sleeper in the world. I sometimes wonder, did I just get lousy sleepers (other than Luke) or is it something I'm doing wrong?!?! Lilah is almost 11 weeks old, and the longest stretch of sleep she's had to date has only been slightly over 3 hours. I put her to bed (as usual) around 8pm last night...and by just after 10, right when I was FINALLY climbing into bed, I saw arms flailing in the crib. Have I mentioned I really don't enjoy sharing a room with a baby? She had unswaddled herself. I re-swaddled her, nursed her and put her to bed. 5 minutes later, she's grunting and fussing. I got her up, nursed her again and put her back in bed. FINALLY, at 11pm, I went to bed. Aaron wakes at 1am for a bottle--I have to go potty anyway, so rather than wake Jeremy up, who, incidentally, fell PROMPTLY to sleep at 10pm, I get up to get his bottle. 2am, she's awake again. I don't even bother to nurse her...what's the point of sitting up for another 30 minutes to an hour at this hour when I FINALLY went to sleep 3 hours ago?!?! I bring her to bed with me. We sleep for a while...until I decide to get comfortable. My movement wakes her up and she starts grunting/fussing. I turn over and nurse her again and succumb to sleeping on my side and trying to ignore the ache that's starting in my hips and back. I don't know how many times this happened...I think she slept reasonably well--it seems that the more tired I get, the less I realize that I'm really uncomfortable. Aaron woke up at 6:45am. Quite early for him...he's teething, plus he DID have his bottle at 1am! I give him his bottle (what's left of it) and he is quiet. There is really no point of TRYING to sneak back into bed, amazingly Lilah did NOT wake up when I got up...so I come downstairs to at least enjoy some coffee and computer time while it's quiet--and to try to figure out what in the world I'm going to do about getting Lilah to sleep better...shouldn't we be well on our way to sleeping thru the night by this point?? At least sleeping in a couple of large chunks? Sleeping in her OWN bed would be fantastic! Oh, did I mention that her naps are rarely more than 45 minutes too? Unless, of course, it's in her swing. I'm sure all of this is related and I'm perpetuating the problem...but at 2am, all I want is sleep...no matter how lousy it is...I take solace in the fact that in approximately 9-10 months, she will probably be sleeping mostly through the night. *sigh*
