Lily's first Milestone

Okay, I'm writing this blog a little excited and a little sad...Lily slept through the night for the past two nights in a row! I'm very happy that she slept through the night (10 - 7 the first night, 11:30 - 5:30 the second night, would have been longer had I not woken her up). However, she slept in our bed, snuggled right next to me. Don't get me wrong, I love cuddling with my baby, but I'm not a huge fan of co-sleeping. I just don't sleep as well with her next to me. The first night I let it slide and brought her to bed at 10 (her normal bedtime is 9, so she had been up for an hour fussing). The second night I tried really hard NOT to bring her to bed. John was all for letting her sleep with us, but I really wanted her to sleep in her own bed. The girl has an aversion to her bed at night. She'll be sound asleep after you've been holding her upright for an hour and as soon as you lay her down in her bassinet, BAM she's awake, spitting up left and right. Bring her to our bed and BAM, she's out like a light and not the slightest dribble is coming out of her mouth. I just don't get it! We're even elevating her bed so she doesn't have issues with spitting up at night.
She has no issues during the day napping in her bed, most of the time. The only time she fusses is in the afternoon right after lunch. During that nap she wants to sleep in her swing. I usually let her b/c she'll sleep a good 2-1/2 to 3 hours during the twins' nap so I get stuff done or take a nap myself. I know I need to let her cry it out and sleep in her bed during that time too, but I don't want her to wake the twins and Jake is just now starting to nap well again.
I'm going to ask the pedi about it Friday when she has her two month check up. Maybe she needs different reflux med? I don't know. If she just fussed, I'd let her just fuss, but since she's spitting up, coughing, gagging etc. I can't just let her stay in her crib and cry it out.
I woke up this morning at 5:30 and tried to move her back to her bassinet, after she'd been sleeping in our bed all night and BAM she was awake spitting up again as soon as her head hit her bed. A little after 6 I finally brought her back to my bed and BAM she was out again and slept till 9:30.
