My daughter (now 16 months) is the same way we rocked her from day one and now you pretty much have to get her solidly asleep before putting her down. With my newborn (now 7 weeks) I just rock her until she's just about asleep and then lay her down. Typically she will just stir for a minute then close her eyes. Sometimes, I use a hand to "vibrate" the crib so she is just kinda rocked a little longer without me actually holding her. She loves to be swaddled, and although its hot, we still do it because it seems to help her go to sleep and stay that way longer. Perhaps, I've just lucked out but she's sleeping 10 hours at night with about an hour break in the middle somewhere to eat. Good luck.
