How's your baby sleeping?

Nay
How are your 4 month old babes sleeping? My baby is 15 weeks and still wakes up twice a night.  She goes down at 7, wakes between 12-1 and then again around 4.  We also usually need to rock her to sleep, I'd like to break that habit so she learns to go to sleep on her own but can't bring myself to let her cry it out!
