Hopefully you'll get some good advice. I just wanted to let you know that we co-slept for all or part of the night until just recently... our son will be 4 in 2 weeks. :)
Our son really never took to his crib - he always needed to be close & know we were near by. We transitioned right from our bed into a toddler bed around 18 months or so, but he is just now sleeping in his own bed in his own room.
Honestly, you'll get lots of opinions, but Chase slept through the night early on, much like your daughter & a good night's sleep was far more important to me than where he slept. I was never a "sleep starved" new mom & I'm happy about that!
Do what feels right for you - there is no "magic secret" & your daughter is too young to self-soothe, so crying it out probably isn't your best option. Personally, I thought "The No-Cry Sleep Solution" by Elizabeth Pantley was a great resource even though we made different choices about the family bed. Also, if you're into a more "attached" style of parenting, you might try looking in the Dr. Sears family of books - great resources as well.
Good luck & congratulations!
