Hi Jamie! Well it definitely could be teething, & what I find works best is Hyland's Teething Tablets. Also (I know you said suggestions OTHER than moving her to her own bed, but....) my daughter co-slept with us (wouldn't have done it any differently) until 11 or so months.She's now 17 months. I loved it. No way can she sleep with us now! LOL! What I find on the RARE occasion she does sleep with us, she wakes up through the night wanting to nurse (I too still nurse 2 times a day, down for nap, down for the night). However, when she sleeps in her own bed, she sleeps through the night like a champ! 10-11 hours straight!! I think they feel & smell you there so they want it, if you're not there they won't be reminded of it! When we switched her to her own bed, the 1st night I put her in there, she woke up 15 minutes later, I took her to bed with us. The 2nd night, she woke up 30 minutes later, I took her to bed with us. The 3rd night, she sleep 2 hours before she woke up, again I then took her to bed with us. After about 4 or 5 nights, she had it down & was sleeping in her own crib. I know every baby is different, but I hope some of this helps.
Good luck & God bless!
