I really think it's time to sleep train DD!

We co-sleep and up until now, I have just given her a boob at night when she whimpers or tosses and turns. So, I know it's *my fault* that she has become used to that during her nightime sleep. I really think she's doing too many nighttime wake ups, they're not even full wake ups, just her frantically searching for the boob to comfort her. I'm ok with keeping one nightime wake up, but I want to get her in her own room in her own crib.

Tell me about your sleep training success stories- what you did, how long It took to work, etc.

I'm not comfortable with CIO, it would break my heart!
